Mokon Div., Protective Closures Co. Inc.
Heating/Cooling UnitMPCA/TC combines refrigeration and heating in a single unit and maintains water temperatures from 40 to 230oF (4 to 110oC) with +/-1oF accuracy. The portable, stand-alone unit can be custom designed to meet process requirements.
Recirculating ChillerRS Series is suitable for laboratory heating and cooling. The recirculating chiller is mechanically refrigerated for subambient operating, providing temperatures from -40 to 167oF (-40 to 75oC). With its small footprint, the unit is suited for use with condensers, extractors, rotary evaporators, diffusion pumps and analytical instrumentation.
Kinetics Thermal Systems
Thermoelectric ChillerThermocube is suitable for use controlling the temperature of a laser or other small equipment. The 1 ft3thermoelectric chiller cools, heats or cycles between 23 and 122oF (-5 and 50oC), providing up to 400 W (when air-cooled) or 600 W (when liquid-cooled) cooling capacity at ambient temperatures.
Solid-State Cooling Systems
Portable Air-ConditionerDesigned to keep electronics operating by providing air-conditioning down to 65oF (18oC), Office Pro 60 provides 60,000 BTU/hr of cooling and operates on 230 V. It incorporates a programmable digital controller for automatic operation and a two-speed fan for airflow control.
MovinCool, Denso Sales California Inc.
Water-Circulating Temperature ControllerVeteran Series temperature controller has microprocessor instrumentation and controls temperature from 30 to 250oF (-1 to 121oC). Unit can include pumps from 0.5 to 3 hp and heaters from 6 to 16 kW. Twin-cylinder design provides a range of temperature control. Cooling is provided via an integral cooling valve mounted to the cooling cylinder, and heating is provided by a flange-mounted heater.
Mold Temperature ControllerDesigned for applications requiring full-feature temperature control in a compact unit, MTC portable hot water system offers 30 psi discharge pressure, which can be upgraded to 50 psi. The unit eliminates pump failures by using industrial-duty pumps with EPDM nickel-resistant mechanical seals rated at 300oF (149oC).
Rack-Mount ChillerDesigned to replace tap water usage in water-cooled equipment, RK-19 provides 2,500 BTU/hr of cooling in a CFC-free refrigeration system. Equipped with a hot-gas bypass to maintain stability to +/-0.1oC over the temperature control range of 41 to 86oF (5 to 30oC), the air-cooled model also has a microprocessor controller.
Tek-Temp Instruments Inc.
Temperature Control SystemTCM-350 for controlling process temperature is offered in standard designs using glycol and hot water with a temperature range of -20 to 35oF (-29 to 2oC). Heating capacities range to 1,200 kW and cooling capacities range to 100 tons. The design eliminates cross contamination among utilities while minimizing the possibility of corrosion in a process vessel jacket, reducing fouling.
Pfaudler Reactor Systems
Chiller/Temperature ControllerDesigned for use with all electric machines, Opti-Temp is a combination mold temperature controller and water chiller. The unit's refrigeration circuit allows operation from 40 to 190oF (4 to 88oC) and from zero to full load. A digital temperature controller allows the desired temperature to be set.
