Bath & Chillers

Product Details:

WEIBER Oil Bath, is a type of heated bath which uses boiling oil as the temperature regulator. Since different oils have different boiling points it is possible to obtain a temperature near to the desired temperature by selecting an oil with a boiling point as close as possible to the desired temperature. The most common oils that are being utilized in oil baths are paraffin, glycerol, silicon oil or cottonseed oil due to their quite odorless characteristics.

Construction Details:

Our refrigerated chillers are double walled convection heated units. Outer body of our re-circulating chiller is constructed out of thick PCRC steel sheet, duly pre-treated with primers for rust proofing and painted with air drying paint/stove enamel/powder coating. The inside chamber of the unit is made of heavy gauge stainless steel sheet of grade ss-304. The unit is provided with top opening cover, made of stainless steel with steel concentric rings.

• HEATING

Indirect heating system is provided in our chiller, comprising of air heaters made of high grade Kanthal A-1wires of suitable wattage. The temperature is evenly distributed throughout the chamber through natural waterconvection mechanism, ensuring a very good temperature sensitivity.



• COOLING UNIT

An energy efficient cooling unit is installed in our recirculatory chiller. We use ISI marked high end CFC free compressors of Kirloskar / Tecumseh make, conforming to latest international standards and guidelines.

CONDENSING UNIT

(1) AIR-COOLED CONDENSOR

Air-cooled condenser is internally grooved finned copper tubes used for high heat transfer area, which not only reduce power consumption, but also bring down the condensation faster. This unit is designed. & verdigris & reduces the resistance, saves energy consumption and ensure good heat exchange.




(A.) COMPRESSOR:

HERMETIC COMPRESSOR

Single stage Reciprocating Compressor. Give the High Efficiency compared to sealed compressors, Less Power Consumption , Accessible for repairing, low noise level, Less Vibrations, Wide Voltage Range, Designed for Extremely High Ambient ,Full warranty etc.


COOLING SYSTEM

The compressor is mounted perfectly to ensure recommended level of sound and vibration.


(B.) REFRIGERATION CONTROL

(a).Low and High Pressure switch of RANCO/Danfoss




Which ensures the compressor and refrigeration system when low pressure will occurs it trip off the compressor. This is the only operator friendly switch can easily reset.

WEIBER nitrogen evaporators (water bath type) are typically used “to concentrate samples before analysis or to concentrate samples before a solvent exchange.When a scientist needs to concentrate a sample that’s in a volatile liquid—like acetone, acetonitrile, or methanol—a nitrogen evaporator can do the job. As a result, scientists use this technology in sample preparation in environmental, polymer science, quality control, and toxicology labs etc.Our nitrogen evaporators utilize adjustable nitrogen blow down technology allowing full control of nitrogen flow to samples, with no wasted nitrogen gas. We combined this technology with uniform efficient heat applied through water baths. This simultaneously maximizes solvent evaporation in the samples being concentrated and saves the lab money.

 

The 24 position WEIBER nitrogen evaporator is our most adaptable version but we can customize it to 6/12/34/50 positions as per the requirement.

 

Special Features:

• Microprocessor based control system.
• Can accommodate samples with an outside diameter of 10-30 mm.
• Provides controlled concentration of sample vials through the application of nitrogen gas within a heated water bath.
• The dual band spring hoist assembly provides a simple and effective means of removing samples from the heated water bath.
• Circular rotating design permits each sample to be accessible from the front of the instrument for easy insertion and retrieval.
• The chrome plated needle valves are individually milled from solid brass, enabling precise, uniform adjustments for your nitrogen blow down.
• Efficient and safe sample reduction with minimal nitrogen waste.
• Long lasting and user friendly technology
• Gas flow can be controlled at each sample position via needle valves
• Nitrogen filter
• High pressure phthalate free tubing for safety, Teflon tubing for no contamination
• Needles, 4 inch x 19 gauge with polypropylene hub and stainless steel shaft
• 220v wiring harness (optional)
• Z-Purge/intrinsically safe purge case (optional)
• Acid resistant coating on instrument and needles (optional)
• Side control box with built-in digital controller, timer, and pressure regulator (optional)

Product Details:

Water cooled chiller is a refrigeration apparatus that produces cold water or water/glycol mix, to cool industrial process equipment or provide comfort cooling for buildings. A water chiller uses the evaporation of a refrigerant to cool the fluid through a heat exchanger. Weiber offers a large selection of water cooled chillers/heater with quality construction and innovative technology, serving a variety of industries. The size and type of equipment used varies from small pre-packed low temperature environmental chambers of only a few horsepower (kW) to large custom-designed and often field-erected systems ranging to several hundred horsepower (kW).

 

The larger units are by nature one-of-a-kind, designed and built for a specific purpose, for a specific duty at a precisely controlled low temperature condition. The large units use a combination of one, two or more refrigerants in open cascade arrangements to obtain the desired low temperature. 7 standard models are available to choose from however we have the capacity to customize the specification as per individual needs.

 

Special Features:

• Precision temperature stability
• Special fluid handling (materials, pumps, filtration)
• Portable and reliable
• Ergonomic designs
• Microprocessor based controller (HMI+PLC based controller option)
• CFC free refrigeration system
• Hermetically sealed compressor
• RS 232 interfacing for remote control and monitoring
• Options for recirculating fluids (see the technical matrix of all models)
  • Water
  • Deionized Water
  • Deuterium Oxide / Methanol
  • Fluorinert FC-3283
  • Ethylene Glycol
• Front to rear airflow
• Audio visual alarms for malfunction
• Castors for ease in mobility

Product Details:

WEIBER industrial chillers (air cooled) is a refrigeration system used to cool a process fluid and dehumidifies air in industrial facilities. Air cooled chiller uses fans to dissipate the heat removed by the refrigeration system. The equipment works as an air conditioning system with the world's best standard A-type screw compressor and newly designed shell and tube heat exchanger that have powerful cooling ability, low noise, low vibration, high efficiency and high reliability. These are equipped where no source of liquid are available for cooling the condenser.

Air Cooled Chiller comes complete with PID microprocessor-controlled controller that utilizes fully proportional cooling and heating. The equipment offers low-stress refrigeration system, circulating pumps, R-134A CFC free refrigerant and fluid reservoir. WEIBER gives you an option to choose from the seven models as per the desired recirculating fluid and other technical parameters.We specialize in both standard as well as customized chillers to meet the demands in required areas.
