Laboratory Recirculating Chillers 1050-3200W

Overview

K1 and K3 Chiller Range

Applied Thermal Control recirculating chillers are built to order to our customers’ requirements, they are designed for use with applications in laboratory, research and manufacturing processes. With over 20 years’ experience supplying chillers from 480W through to 15kW cooling capacity we offer expert, supportive and consultative pre-sales advice with free technical support from our experienced engineers, research and development team.

Our precision chillers benefit from a compact design with a small foot print, they can be easily moved on casters between applications or experiments and most of the range can effortlessly be stored on or beneath a bench.  Offering accurate temperature control to 0.1°C precision with a choice of recirculating chillers, water-to-water heat exchangers and air blast coolers.

Providing great reliability and consistent temperature stability the ATC range of chillers are quiet in operation and available with a range of pumps and standard options to suit your needs.  Each chiller is specifically designed and manufactured to suit each customers requirement. We have experience in working with food manufacturers, cosmetics producers, scientific instrument support markets (electron microscopes, X-ray diffraction, ICPMS etc.), semiconductor process, breweries, ophthalmic lens manufacturing equipment, induction heating, and more recently the chillers of choice for commercial digital printing and laser lithography markets worldwide.  

With a robust design, supporting research and applications that are “always on” ATC chillers offer great reliability with up to 15kW cooling capacity. Available as UL-CSA compliant via ETL Mark option on both indoor and outdoor chillers.

The use of precision recirculating chillers can help to comply with organisational environmental policies.   By using accurately cooled house water, processes can be economical and environmentally friendly.

We supply worldwide, our chillers have a variable power supply, allowing for easy change of voltage or frequency supply from one region to another at a flick of a switch.  This is backed by an extensive network of trusted partners and skilled service agents to support our global customers. 

We can offer service contract options to support your chiller in use. With UK based factory trained emergency call out engineers who can assess and if necessary fix on site, minimising the need to return units to base for repair resulting in reduced application down time.

      Remote Alarm Pack
      The compact remote alarm pack indicates the chiller status when the chiller is located away from the main application.
      Low Temperature Pack
      This low temperature option can be fitted to allow a chiller to be operated below +4°C and to be controlled down to -15°C.
      Heater Pack
      The heater pack element can provide an accurate and efficient temperature control up to 65°C.
      Water Cooling – K1
      This option can be built into all K1 chillers and is used where you have a central or house water supply.
      Non Return / Solenoid Valve
      The non-return/solenoid option can be fitted to prevent back siphoning of fluid into the chiller during maintenance.
      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.
      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 deioniser provides very high levels of purity in recirculating water.
      Water Cooling – K3
      This option can be built into all K3 chillers and is used where you have a central or house water supply.
