Product Details:

Water distillers produce highly treated and disinfected water for laboratory usage. The distillation process removes minerals and microbiological contaminants and can reduce levels of chemical contaminants.The complete unit is made of Stainless Steel with triple vapour baffle. The lid is automatically sealed with water forming is a recess in the head of the still into which the flange of lid rests which minimises the loss of steam.

 

Working Prinicple:

A water distiller works by boiling water into water vapour, condensing it and then returning it to its liquid state. It is collected in a storage container.

Water distillers are neither intended to treat water that is visually contaminated nor intended to convert waste water to safe, microbiologically.

The process occurs in several steps:

• Municipal or well water is manually or automatically fed into the distiller unit’s boiling chamber.
• A heating element in the boiling chamber heats the water until it boils.
• The steam rises from the boiling chamber. Volatile contaminants (gases) are discharged through a built-in vent.
• Minerals and salts are retained in the boiling chamber as hard deposits or scale.
• The steam enters a coiled tube (condenser), which is cooled by cool water.
• Water droplets form as condensation occurs.
• The distilled water is collected in a storage tank. If the unit is an automatic model, it is set to operate to fill the storage tank.

Product Details:

Our laboratory ball mill takes care of any pulverizing, milling or grinding job that you can give it. Its multifunction design allows it to handle wet or dry, brittle or fibrous materials. Weiber Ball mills are fitted with FHP motor. The unit drives with maximum speed of 80 rpm. The jar is made of aluminum and having steel balls of different sizes to be put in jar for mixing and grinding pesticides powder. Jar is interchangeable and easily removable, light in weight and compact unit working on 200 volts AC.

 

Working Principle:

The sample material is primarily crushed by the high-energy impact of grinding balls together with friction between the balls and the wall of the grinding bowl.

 

The grinding bowls with material and balls rotate around their own axis on a counter-rotating supporting disc. The centrifugal forces caused by the rotation of the grinding bowls and supporting discs work on the contents of the grinding bowls. The force resulting from rotation of the grinding bowl when the mill is started causes the rotating balls to rub against the inside wall of the bowl thus crushing the material.

 

At a certain point in time the stronger centrifugal force of the supporting disc causes the grinding material and balls to separate from the inner wall of the grinding bowl. The grinding balls cross the bowl at high speeds impacting with the grinding material on the opposite wall - creating size reduction by impact.

Working Principle:
Light from LED light source is focused on the underside or a prism element. When a liquid sample is applied to the measuring surface of the prism, some of the light is transmitted through the solution and lost, while the remaining light is reflected onto a linear array of photodiodes creating a shadow line. The refractive index is directly related to the position of the shadow line on the photodiodes. Once the position of the shadow line has been automatically determined by the instrument, the internal software will correlate the position to refractive index, or to another unit of measure related to refractive index, and display a digital readout on an LCD or LED scale.
 
Applications:

Food Industry: Our Digital Brix Refractometer is used in the food industry for measuring the approximate amount of sugars in fruits, vegetables, juices, wine, soft drinks and in the sugar manufacturing industry. Different countries use the scales in different industries. Our digital brix refractometers calculate the Brix value based on refractive index. These meters are portable, splash proof and very simple to use, so that they can be operated by anybody directly on location.

More and more often Brix is measured to determine ideal harvesting times of fruit and vegetables so that products arrive at the consumers in a perfect state or are ideal for subsequent processing steps such as vinification

SCIENTIFIC USAGE: When a refractometer is used, it is correct to report the result as "refractometric dried substance" (RDS). One might speak of a liquid as being 20 °Bx RDS. This is a measure of percent by weight of TOTAL dried solids and, although not technically the same as Brix degrees determined through a specific gravity method, renders an accurate measurement of sucrose content since the majority of dried solids are in fact sucrose. When an infrared Brix sensor is used, it measures the vibrational frequency of the sugar molecules, giving a Brix degrees measurement.

Working Principle:

Weiber dehumidifier removes moisture from the air, thus lowering the humidity. It does this by condensing water onto a cold surface. A fan is used to speed up the process. It blows warm air onto cold metal coils, and the resulting water drips into a water collector. The resulting cold air is then passed over warm coils to bring it back to room temperature. The air is then reheated and sends back to the room.

 

Applications:

Dry Air Storage (Multi Purpose) :

In dry air storage our dehumidifier keeps the relative humidity at the desired level all year round regardless of the temperature. Basic dry air storage only requires an un insulated, reasonably airtight, building fitted with a dehumidifier. Steel and other metals, wood, paper, pulverized products, military equipment are just a few examples of items possible that can be stored safely and at low cost.

Production Facilities (Pharmaceutical):

Weiber dehumidifiers make it possible to produce pharmaceutical products all year round in a controlled dry atmosphere. These dehumidifiers increase production capacity in spray dryers and fluidized beds that are used, for example, in the food industry. Breweries can avoid mould and condensation on cold surfaces by using dehumidifiers

Archives:

Archives for photographic film must be kept at low temperature and at low relative humidity, typically + 2 ºC, 30% RH. A controlled climate with stable relative humidity is also vital to prevent art collections, old documents, textiles, books etc from being damaged by the ravages of time.

Power Plants And Buildings:

Being able to supply dry air inside industrial facilities and buildings is an important capability. Power plant boilers, piping, steam condensers, turbines and bridges are examples of dry air corrosion protection methods. Buildings that have suffered flooding or moisture damage can often be made fully functional again after drying out with dry air.

Product Details:

The objective of the wet sieve test is to obtain basic index information about the soil, that can be used to estimate strength and permeability. It is the primary form of classification for granular soils.

 

There are some materials which, when tested dry, produce less than accurate particle analysis results. If the material is not soluble in water and reproducible results are difficult to obtain, then wet testing may be the method required to produce accurate data. This kit offers an alternative to hand wet wash sieving using a single tall-frame wet wash sieve. It has been specifically designed for use with the Weiber wet Ro-Tap sieve shaker and a stack of standard full-height testing sieves.

 

Working Principle:

A gradation test is performed on a sample of aggregate in a laboratory. A typical sieve analysis involves a nested column of sieves with wire mesh cloth (screen). A representative weighed sample is poured into the top sieve which has the largest screen openings. Each lower sieve in the column has smaller openings than the one above. At the base is a round pan, called the receiver.

 

The column is typically placed in our wet sieve shaker. The shaker shakes the column, usually for some fixed amount of time. After the shaking is complete the material on each sieve is weighed. The weight of the sample of each sieve is then divided by the total weight to give a percentage retained on each sieve.

 

The size of the average particles on each sieve then being analysis to get the cut-point or specific size range captured on screen.

 

The results of this test are used to describe the properties of the aggregate and to see if it is appropriate for various civil engineering purposes such as selecting the appropriate aggregate for concrete mixes and asphalt mixes as well as sizing of water production well screens.

Benefits of Using an Automated Test Sieve Shaker for Particle-Size Analysis:

• More Consistent and Accurate Results- The first mechanical test sieve shaker was designed to replicate the hand motions used in manual testing scenarios. By automating this process, test sieve shakers are able to provide a much higher level of continuity throughout the testing process. As a result, they can produce more accurate and repeatable results regardless of when or where a test is performed.
• Increased Efficiency- Manually shaking test sieves is both time consuming and labor intensive. A mechanical sieve shaker is able to replicate and replace the human input needed to perform this type of testing. This means that more material can be tested in less time and with fewer resources invested.
• Cost Savings- Employing humans to conduct these tests represents ongoing costs in the form of wages and fringe benefits. In addition, downtime related to illness or personal absences also translates into lost productivity and increased opportunity cost. The modern shaker is both reliable and durable. As a result, it doesn't require a lot of expensive maintenance or need replaced often. Over time, these factors can translate into substantial cost savings

PRE – TREATMENT : TO PROTECT THE SYSTEM

Spun Cartridge Filter

The micron cartridge filter is provided for fine filtration of suspended solids. Filter is good for the removal of relatively uniform sized particles throughout the body of the filter.

When to Replace a Filter Cartridge

As particles accumulate on a filter cartridge, flow through the filter becomes restricted. This restriction reduces the flow rate through the cartridge and increases backpressure Thus the Cartridge filter should be changed when the flow drop or pressure drop is considerable.

Granular Activated Carbon

The granular activated carbon to eliminate free chlorine and colloids present in tap water that may otherwise alter the taste and color of your water supply.

Spun Cartridge Filter

The micron cartridge filter is provided for fine filtration of suspended solids.

Product Details:

Deionizers (DI) remove both cations and anions, releasing hydrogen ions (H+) in exchange for the former, and hydroxyl ions (OH-) for the latter. The hydrogen and hydroxyl ions subsequently combine to form pure water.

 

Deionizers are most commonly used when ionic contamination is such that reverse osmosis alone cannot be relied upon to produce water of acceptable quality. In such most instances, mixed bed deionizers may be placed downstream of the reverse osmosis unit, completing the purification process.A wide variety of public water vending machines as well as many industrial applications in the electronics industry operate in this manner.

• A third tank polisher can be accommodated under the single control to pick up sodium or silica leakage, allowing you to easily attain higher purity water at less expense.
• A single set of printed circuit boards control both simultaneous and sequential regeneration. You simply select the desired regeneration mode with DIP switches.
• All programming features are easily accessible on the front panel, so there's no need to enter the control box and disrupt operations.
• Modular construction reduces downtime and simplifies troubleshooting and service.
• A low level sensor can be easily wired into the control to warn of low chemical volumes.
• Provisions for a remote control panel and auxiliary "START REGENERATION" source allow regeneration to be initiated and controlled from a location remote from the actual installation site.
• Level controlled shutoff to a product storage tank can be utilized with the addition of a simple float switch in the storage tank.
• Relays and fuses on the power printed circuit board provide for the operation of recirculation and supply pumps.

 

Working Principle:

The two-bed deionizer consists of two vessels - one containing a cation-exchange resin in the hydrogen (H+) form and the other containing an anion resin in the hydroxyl (OH-) form. Water flows through the cation column, whereupon all the cations are exchanged for hydrogen ions.To keep the water electrically balanced, for every monovalent cation, e.g. Na+, one hydrogen ion is exchanged and for every divalent cation, e.g. Ca2+, or Mg2+, two hydrogen ions are exchanged. The same principle applies when considering anion-exchange. The decationised water then flows through the anion column. This time, all the negatively charged ions are exchanged for hydroxide ions which then combine with the hydrogen ions to form water (H2O).

 

Construction Details:

It consists of an in-built pre filter and very high exchanging capacity non-corrosive CATION and ANION resin columns pre-fitted with imported RESINS for efficient results having treated water parameters conforming to IS- 1069/64.

WEIBER table Top Sieve Shaker assists in producing uniform motion for shaking. The vibration is controlled by speed regulator. It is used for research and development, quality control of raw materials, as well as in production monitoring.

 

Working Principle:

The vertical throwing motion is overlaid with a slight circular motion which results in distribution of the sample amount over the whole sieving surface. The particles are accelerated in the vertical direction (are thrown upwards). In the air they carry out free rotations and interact with the openings in the mesh of the sieve when they fall back. If the particles are smaller than the openings, they pass through the sieve. If they are larger, they are thrown upwards again. The rotating motion while suspended increases the probability that the particles present a different orientation to the mesh when they fall back again, and thus might eventually pass through the mesh.

 

Applications:

The size distribution is often of critical importance to the way the material performs in use. A sieve analysis can be performed on any type of non-organic or organic granular materials including sands, crushed rock, clays, granite, feldspars, coal, soil, a wide range of manufactured powders, grain and seeds etc.
