Standard Options

ATC have designed a range of commonly requested options which can be specified into the chillers, as required by the user. In addition to these a range of special options can be specified, please discuss your requirement with us.

Applied Thermal Control supplies a range of quiet and discreet, precision recirculating chillers from 1637 BTU to 47769 BTU (480w to 14kW) cooling capacity, providing temperature control to 0.10°C (32°F) accuracy.

Our extensive chiller expertise and flexible design allow us to work with our customers to develop bespoke designs and manufacture models to OEM requirements. Supplying a range of recirculating coolers, water to water heat exchangers and air blast coolers we can advise on the most suitable solution for your needs. We are proud of the performance and reliability of both our standard and custom chillers and the professionalism which supports these products worldwide.

For more details, please select a product from the list below.

Remote Alarm Pack
The compact remote alarm supplied by Applied Thermal Control is sited close to the application, allowing personnel to monitor the chiller, without needing to see the chiller. The display indicates normal operation, or shows alarms for temperature and fluid (both flow and level). An audible siren also sounds in an alarm condition. The alarm box can be mounted up to 15 meters away from the chiller, and is fitted with an emergency stop switch that will turn off the chiller should it be necessary.
Low Temperature Pack
This low temperature option can be fitted to allow a chiller to be operated below 39.2°F (+4°C) and to be controlled down to 5°F (-15°C).
Heater Pack

The normal upper limit of the process temperature is 35°C. It is possible to raise this up to 149°F (65°C) by means of a heater pack (higher temperatures can be achieved, following discussion with an ATC salesperson). Heater packs are typically installed into chiller systems where it is necessary to maintain a specific temperature range, and the cooling capacity of the chiller alone is not sufficient to achieve the desired range

Water-Cooled Condensers
Water-cooled condensers are commonly used in chillers to remove heat from the refrigerant and transfer it into a primary cooling circuit. In a recirculating chiller system, the refrigerant absorbs heat from the process or space, and transfers it to the water-cooled condenser.
Non Return / Solenoid Valve

Non-return/Solenoid valves work by using an electrically activated solenoid to control the flow of fluid through the valve. When the solenoid is energized, a magnetic field is created, pulling the valve plunger into the valve body, opening the flow path. When the solenoid is de-energized, a spring in the valve pushes the plunger back into its original position, closing the path again.

The use of solenoid valves can offer several benefits, including:

Quick response time

Solenoid valves are able to open and close quickly, allowing for fast and accurate control of fluid flow, making them well-suited for use in process cooling systems where precise temperature control is required.

Easy to control

Solenoid valves are controlled with a simple electrical signal, making them easy to integrate into to control systems to automate processes.

Compact size

Solenoid valves are small and relatively lightweight, making in possible to install them into tight spaces or systems that have limited room available for components.


Solenoid valves are constructed of materials that are resistant to corrosion and wear, suiting them to use in harsh environments.


Solenoid valves are low in cost when compared to other types of valves, making them an attractive option for many applications.

While solenoid valves offer many advantages when used in process cooling equipment, there are also some drawbacks to consider:

Electrical dependence
  • Solenoid valves rely on an electrical current to operate, which means that they are not suitable for use in applications where there is no electrical power available. If the electrical power is disrupted or fails, the valve may not operate as intended.
Limited flow control
  • Whilst solenoid valves are able to open and close quickly, they are not typically designed with fine flow control in mind. If precise control of fluid flow is required, additional measures may be required. 
Limited pressure range
  • Solenoid valves are designed for use at low to medium pressures, but may not be suitable under high pressures.
Maintenance requirements
  • As with any component, solenoid valves may be subject to wear and tear, and may require replacement over time. If exposed to high temperatures or corrosive fluids, the solenoid coil can become damaged.

When used in process cooling equipment, solenoid valves are often used in conjunction with other components such as temperature sensors, flow meters, and control systems to ensure efficient and accurate control.

Solenoid valves are often fitted to prevent back siphoning of fluid into the chiller when it is turned off for refilling or maintenance.

They are recommended when the chiller and application are at different levels (more than 2 meters height difference), or where a long length of flexible tubing is used between the chiller and the application. It is also advisable to add non-return/solenoid valves in situations where pipe-runs will be going up into ceiling ducts.

Quick Release Connectors
All ATC chillers can be fitted with self-sealing quick release fluid connectors allowing a quick and easy chiller exchange. 
Installation Kit
Reinforced black 1/2" tubing and fittings to connect the chiller to an application.
Air Filter MA 145/119
Air filters work by removing contaminants and impurities from the air that circulates through the cooling system. This helps to protect the equipment from damage, maintain its efficiency, and ensure the quality of the cooled process.
Castors – KT
Where mobility is required, KT chillers can be fitted with 2 locking castors.
RS 485 Comms
Optional communications ports for RS-485 allow continuous monitoring of temperature and alarms by an external computer.
In-line Deioniser
The optional in-line deionizer provides very high levels of purity in recirculating water.
Low Flow Alarm
Low flow alarms are a type of warning system that is designed to alert operators or maintenance personnel when the flow of heat transfer fluid through process cooling equipment falls below a certain level. The purpose of these alarms is to help to prevent damage to the equipment and other connected applications by ensuring that adequate heat transfer fluid flow is maintained.
Standard Volt Free Connection (VFC) Set
Optional VFC set allows for monitoring of alarms through analogue signal. 
Stainless Steel Pump and Fittings
Stainless steel parts are standard on all ATC machinery.

Fan Speed Control (on/off)
A fan speed control (on/off) option allows the fan to be turned off when not needed, saving energy and reducing noise. 
Fan Speed Control (proportional)
A fan speed control (proportional) option allows a fan speed controller to slow the fan motor, reducing noise levels and energy.

Addition of the flow meter pack output allows the flow rate to be communicated via RS485.
Seismic Mounts
Seismic mounts protect your chiller in the event of ground tremors, allowing you to fix the chiller to the ground via brackets. 
In-line UV Decontamination
Use of an in-line UV decontamination pack will prevent any growth within the system by passing fluid through steel tubes containing a UV lamp. 
Qwikfoot Kit
Addition of the Qwikfoot kit allows the chiller to be mounted and lifted off the ground, providing an anchor with no need to drill into the floor.
Stainless Enclosure
This robust stainless steel enclosure will protect your chiller from the elements, and will withstand more aggressive cleaning materials.
