Overview

Combining operational excellence and technology expertise with an intimate understanding of customer's need, LabTech offers a complete line of recirculating water chillers with CE marks. These state-of-the-art water chillers ensure accurate and constant cooling conditions for instrumentation in the harsh environment of the laboratory.

With PID temperature control, the H series water recirculating chillers have better temperature control, greater energy efficiency, and longer compressor life time.

Technical Features:

  • High Energy Efficiency - “Hot gas bypss” technology routes back the hot, uncondensed refrigerant through a reservoir coil, thus eliminating on/off cycling of compressors and the addition of energy-wasting heaters. This method ensures better temperature control and greater energy efficiency.
  • Accurate Temperature Control - P.I.D. is a dynamic temperature control technique through proportional, integrative and differential control.
  • High Quality and Long Lifespan - Reliable components and top materials evaluated by the strict quality control procedure make LabTech chillers more solid and durable.
  • High Performance and Quiet Operation - LabTech chillers, ensure quiet operations and low water consumption while providing rapid and powerful cooling ability.
  • Operation Safely and Environmental Friendly - Intelligent alarm functions ensure safe working condition for your instruments. The refrigerant of CFC-free R134A cryogen is compatible with international environmental standards.
  • Best Quality/Price Ratio in the Market

FAQ

What are the size of the inlet / outlet ports on the H Series chillers?

They are ½ pipe thread size (.84”O.D.) ports.

 

The H Series chillers list a maximum pump flow; is the pump flow adjustable?

All H Series Recirculating Chillers have a relief valve that can be used to adjust the unit’s operating pressure and flow rate. There is a pressure gauge built into the front of the instrument to read the relief valve setting. By releasing pressure through the relief valve, a lower flow rate can be achieved.

 

Is it okay to run an H Series chiller at maximum load and under continuous operation?

The H Series chillers are designed for continuous operation, but it is not recommended that you do so under maximum load. Likewise, running at maximum load is acceptable for non-continuous usage. Like any equipment, the more stress the unit experiences the shorter the lifespan will be, however running an H Series chiller continuously at max load leads to a high failure rate.

 

Are the H Series Recirculating Chillers UL listed or CSA certified?

Currently only the H50-500 is UL listed. None have CSA certification.

 

Do the H Series Recirculating Chillers have a low-level shutoff?

Yes. If the water level gets too low in the reservoir, they will automatically shut off.

 

How are the H Series Recirculating Chillers cooled? What is the refrigerant used?

The H Series Chillers are compressor cooled. The H50 and Smart H150 series both use R134A refrigerant. The H150 series uses R404A refrigerant.
