LabTech H Series Recirculating Water Chillers

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.

The cooling capacities do not list corresponding temperatures. At what temperature is the cooling capacity given?

The cooling capacities are at 25°C unless otherwise stated.
