The TH series chambers are our state of the art freezer environmental chambers used for a variety of applications. Controls are able to be quickly exchanged for future upgrades or repair.

Widely Proven, Non-Proprietary Controllers

Standard controllers for the TH Series are manufactured by Fuji Electric and are ideal for laboratory freezer. Unlike many proprietary controllers, this controller is commercially available and proven in tens of thousands of installations. Standard functions include: autotuning, fuzzy logic, PID control, programmable alarms, calibration capability, offset capability, etc. A touchscreen control interface is optional. Other controller manufacturers are also supported (Watlow, Allen-Bradley etc.)

Greatly Reduced Direct and Indirect Energy Loads

The TH Series freezers utilize less energy than comparable freeze thaw chambers and introduce less impact upon building cooling systems. This efficiency “dual benefit” allows our chambers to be located in spaces unsuitable for other chambers.

Services and Warranties

We offer technical support throughout the lifetime of your freezer. In addition to standard warranties, we also offer extended warranties for cooling components, parts and labor. We also provide qualifications, validations and preventive maintenance services at an additional cost. Please ask for a quote.

Refrigeration System

Refrigeration system factory balanced using CFC free 404A refrigerant.

Top mounted condensing unit.

Cooling surfaces act as dehumidifying modules at 25°C/60%RH and 30°C/65%RH

Factory pre-engineered capillary tube system with oversized condenser and evaporator to reduce product pull down time and to consistently maintain interior cabinet temperature (non-adjustable capillary tube system superior to problematic expansion valve).

Evaporator – epoxy coated at the time of manufacture to eliminate the potential of corrosion.
