The "Greening" of America spurs new initiatives on the commercialization of temperature control systems.

The checklist of commercial products slated for the scrapheap grows daily as the green movement casts its shadow over the United States. For example, old-technology, old style refrigeration is one such violator headed for extinction. Reducing gaseous emissions from refrigeration systems (e.g. Freon, R-134A) and all sources of CO2 emissions are reshaping the high-tech landscape of temperature control systems.

By applying a heat source on one side and a cooler heat sink to the opposite side modern thermoelectric materials produce electric power. Arrays of these thermoelectric materials form solid state heat engines. These engines also can be used in reverse so that electric power is converted directly to cooling and heating.

Best-in-Class Temperature Control Systems:

• Hermetically sealed scroll compressor with fewer moving parts. .
• Accurate temperature control with microprocessoror Allen-Bradley PLC (Programmable Logic Controller)
• Brazed plate evaporators for highest heat transfer

Top Considerations before Buying Temperature Control Systems:

A key aspect in a temperature control system (cooling system) purchase is to pre-plan use. For example, single-circuit systems offer an economical means of single-source chilling, while a multiple-circuit system allows chilling from two or more circuits for varying load conditions.

Key Providers:

1. Tek-Temp Instruments, Inc. was founded in 1985 with the objective of developing quality products in the heat transfer equipment field. The company is engaged in the development and manufacturing of precision temperature control liquid chillers, water chillers and heating / cooling systems.

Tek-Temp handles heating & cooling for medical, industrial, multi loop, independent and control, channel fab, plus; clean room, equipment, RS-232, GPIB, Plasma Etch, CVD, PVD, air, cooled, water, evaporator, and condensers. In addition, the company offers laser chillers, fiber chillers, and optic refrigerated chillers.

2. Burkert Fluid Control Systems applies its measurement, control and regulation technology to engineering systems and solutions for water, steam, gases and other fluid media with products that include solenoid, process and analytical valves, pneumatic actuation, sensors and controllers. The company provides individual products as well as complete system and application solutions, from initial planning to after-sales support. Founded by Chriatian Burkert in 1946, Burkert is now in 35 countries. The company operates in the categories of industrial measurement, control and fluid technology. General product lines include fluid control systems; systems for measuring, controlling and regulating gasses and fluids from individual valves, sensors or controls up to complete automation solutions and fluid systems, as well as hygienic processing, steam, water treatment, cooling systems, gas handling, microfluidics.

3. Ernst Flow Industries operates in the field of liquid level and fluid monitoring instruments, developing and manufacturing valves, pneumatic equipment components, flow sensors, flowmeters, and temperature sensors.  The company, the result of a 2002 merger between Ernst Gage Company and Eugene Ernst Products Company, combines over 90 years of flow industry expertise. The company's product line includes washers, gaskets, glass, flowmeters, pressure gages, temperature gages, vacuum gages, level gages, polytetrafluoroethylene (PTFE) seals, packing seals, flow switches with indicator, liquid level switches, thermometers, ball valves, flanged valves, needle valves, plastic valves, and shut-off valves.

4. General Electric's Division of Sensing& Inspection Technologies develops sensing elements, devices, instruments, and systems that monitor, protect, control, and validate critical processes and applications, among which are its multivariable flowmeters and Coriolis mass flowmeters. Additionally, the company designs and develops precision instruments and systems which measure temperature, pressure, liquid level, humidity, gas concentration, and flow rate applications, including ultrasonic and vortex. The company’s technologies and solutions include thermal validation, dew point measurement, ultrasonic and gas flow measurement, control circuit protection, liquid level detection, process control instrumentation, and microstructure design. In 2009, the company signed a pressure contract with Honeywell, the contract also includes production, aftermarket and spares; and also launched ACCUSOLVE and Kaye RF ValProbe 1.1. In 2008, the company introduced a new corrosion-resistant, submersible level probe that offers level measurement in a wide variety of applications. Also in 2008, the company acquired Rheonik, a leading manufacturer of high accuracy coriolis mass flowmeters used in the oil & gas, process and power industries.

Temperature Control Systems
Definition: A temperature control system programs, sets and maintains levels of heat or air conditioning (cold) as needed and maintains these settings for the duration of the system's programmed operation. The controller itself, containing a circuit board and memory chip, is a digital device that controls temperature operation from pre-programmed set points.
