0-15kW Rack Mounted Water to Water Heat Exchangers

The XR-Series is a range of 19” rack mountable water-to-water heat exchangers, designed for use with primary water circuits, providing cooling to applications for which the facilities water may be unsuitable. Water-to-water heat exchangers can address water quality concerns, overcoming issues associated with insufficient pressure, fluctuating flow, or very cold water, by providing a stable supply of coolant to the process, regardless of facility water condition, ensuring that processes remain at optimum performance. They are also effective at protecting more sensitive equipment from microbial contamination.

A water-to-water heat exchanger sits between the application and the primary water circuit, modulating the flow rate to achieve temperature stability without the need for a refrigeration circuit. They are ideal in situations where the application set point is higher than the primary water supply, as the set point does not need to be lower than the primary circuit temperature.

The XR-Series is a self-contained system, comprised of a modulated primary supply, the water-to-water heat exchanger, and the coolant storage tank. A wide range of non-ferrous/stainless steel pumps are available, both positive displacement and centrifugal, with varying flows and pressures to suit a multitude of requirements. All pumps have fan-cooled electric motors and are supplied in 304 & 316 stainless steel as standard.

The XR-Series is suitable for use with a wide range of fluids, including:

Water
Glycols
Oils

Features of the XR-Series include:

Supplied complete with circuit breakers and on/off switches.
Coolant pump starting contactors
Pump motor protection
IP54 protection.
24V control circuit available

XR-Series Cooling Capacity

4kW Cooling Capacity

8kW Cooling Capacity

Heater Pack

The normal upper limit of the process temperature is 35°C. It is possible to raise this up to 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.

More Details

Non Return / Solenoid Valve

The non-return/solenoid option can be fitted to prevent back siphoning of fluid into the chiller during maintenance.

They are recommended when the chiller and application are at different levels (more than 2 metres 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.

More Details

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.

More Details

Quick Release Connectors

All ATC chillers can be fitted with self-sealing quick release fluid connectors allowing a quick and easy chiller exchange.

More Details

Installation Kit

Reinforced black 1/2" tubing and fittings to connect the chiller to an application.

Castors – KT

Castors enhance mobility for large process cooling equipment, aiding in repositioning, maintenance, and space optimization. While most units include castors as standard, they're optional for the KT, W, and larger XF series models. Their inclusion reduces risks, eases movement, and improves facility layout flexibility.

More Details

In-line Deioniser

The optional in-line deioniser provides very high levels of purity in recirculating water.

More Details

Particulate Filter

Particulate filters are designed to remove solid particles from heat transfer fluids. They efficiently capture particles larger than the filter's pores, preventing debris accumulation that can harm equipment and reduce system efficiency. These filters can be strategically positioned throughout the system and require regular maintenance to ensure peak performance. Applied Thermal Control offer a versatile 10"10-micron filter in a plastic housing, with multiple mounting options, allowing customers to tailor filtration solutions to their specific needs.

More Details

Fan Speed Control (on/off)

On/off fan speed control uses a thermostat to toggle a fan's operation based on a set temperature. As the temperature exceeds the set point, the fan runs at full speed until it drops below that threshold, at which point it stops. This method offers various benefits, including simplicity, cost-effectiveness, and energy savings. It's ideal for environments with low thermal mass or non-critical temperature control, and it's particularly advantageous in places with significant temperature variations, like Toronto, to prevent overcooling.

Stainless Enclosure

This robust stainless steel enclosure will protect your chiller from the elements, and will withstand more aggressive cleaning materials.
