The Applied Thermal Control (ATC) K4 cooler is a powerful laboratory chiller with precision cooling performance. It is built to order to customers’ requirements and designed for use with applications in laboratory and industrial manufacturing processes. ATC manufactures a ariety of chillers from 480W through to 15kW cooling capacity.
The K4 chiller offers 4.5kW of cooling in a versatile package. A full range of options and voltage variants are available to customize the K4 unit.
Thermal systems are integral to myriad processes that drive industries of all types, from semiconductor processing and energy generation to medical and foodservice equipment and beyond. Found within each of these industries are sensitive processes that require varying levels of temperature regulation. For instance, when a manufacturing process molds and shapes metal, equipment needs to maintain a temperature above a certain threshold, but an exact temperature may not be necessary. However, another process that involves melting plastic may need to reach a certain temperature but not exceed it—or the material will start to burn.
In those situations for which precise temperature control is required, closed loop systems offer the ability to closely monitor and compensate for environmental changes.
Closed loop temperature control incorporates sensors and ongoing feedback to the system to continually regulate temperature based
Kalrez O-Rings from IES for Semiconductor Applications
Purity is critical to high wafer yield, and Kalrez® seals are designed with properties that help reduce contamination from particulates, outgassing and extractables. Semiconductor Processing Seals
Kalrez® seals for semiconductor processing are field-proven in the manufacture of semiconductor chips.
They can help extend planned maintenance intervals, and thereby lower long-term cost of ownership, in a wide range of semiconductor processes.
The cooling of X-Ray equipment is crucial, especially when it’s part of a highly advanced three-dimensional imaging system. When Thermal Exchange Ltd, now part of Applied Thermal Control, was approached by a renowned manufacturer of X-ray inspection equipment to provide a bespoke x-ray cooling cooling solution, they immediately set about establishing their requirements and were soon designing the initial prototypes.
The first challenge was to provide a machine with sufficient cooling capacity in the available size envelope. Cooling power vs. size ratio however wasn’t the only problem; the customer also required a computer interface capable of monitoring an array of system conditions in order to protect their valuable equipment, and, inverter drive technology had to be employed to handle the variable load conditions of the fluid circuit. This all required considerable engineering and a great deal of computer modelling before an acceptable design
[Posted 2021-10] Telemark now offers recirculating cryochillers for cannibis extraction. Systems include Cryochiller, refrigerant lines, and cooling coil. Successive batches of ethanol can be cooled from room temperature to -40C in approximately 35 minutes (initial cool-down of tank and first batch of ethanol requires approximately 50 minutes).

House water does the heavy lifting for many cooling applications throughout industrial and semiconductor fab manufacturing facilities; but there are a wide range of applications that require or benefit from a 'point of use' or 'process' temperature control unit.
Advantages of using chillers for process cooling include:
The ability to operate across a range of ambient conditions at variable loads, from -20C to +70C
The ability to maintain constant and precise control of the process temperature, to +/- 1° degree C
The cooling fluid is delivered directly to the application heat source
Cooling is independent of the ambient conditions
The ability to minimize potential contamination of the process by using a closed-loop water circuit
Temperature Programmed Oxidation (TPO) is an analytical technique capable of characterizing catalysts and is an important consideration for research and development.
The performance of TPO requires a furnace or microreactor capable of increasing temperatures of a catalyst in precise increments up to extreme conditions, for example in brackets of 1-20°C min-1 up to 1000°C. An integrated mass spectrometer allows for constant real-time analysis of catalytic activity throughout a given thermal reaction, in which a gas mixture will flow over a catalyst throughout an incrementally programmed temperature rise.
Temperature programmed reduction (TPR) is a material characterization process commonly used in catalysis studies to examine the surface chemistry of metals and metal oxides under varying thermal conditions. TPR-enabled mass spectrometry equipment can acquire quantitative and qualitative data relating to the reducing gas mixtures that are made to flow over metallic samples. This process is integral to catalyst investigation as it provides accurate insights into catalyst reducibility and reaction rates in the presence of metal surfaces, informing conclusions on catalyst reproducibility and supporting quality control of existing catalytic substances by setting benchmarks or reduction profiles that ideal manufactured catalysts should adhere to.
[ Posted 2020-07 ] Watlow’s PM PLUS™, the enhanced EZ-ZONE® PM, is now more intuitive and features an enhanced interface for easier programming and readability with a SMOOTH-TOUCH™ keypad creating an industry leading user experience.

The PM PLUS improves the user experience by reducing the complexity at the front of the control while eliminating the dependency of cables when configuring the product. More informationContact Us
To create a Closed Loop Temperature Control circuit you need at least 4 things, usually 5:
1) Heater
2) Power Switch
3) Controller
4) Sensor 5) Limit Controller with additional sensor (optional but highly recommended)
Heater: This already exists in your oven or furnace. Determine the power (voltage, wattage, amperage) and number of phases. If it is three phase, determine if you need to switch two legs or three, which can be noted by the number of fuses on the main power leading to the heater(s) in your current configuration (see related post).
Power Switch: From this power and heater info you can select the power
