Liquid Temperature Control Equipment Options

A wide variety of liquid temperature control equipment is produced by PolyScience. In most cases products are not designed for a particular application but are rather engineered to offer stable heating or cooling over common operating temperature ranges. Depending on the application, if you need to maintain a temperature below or near ambient temperature then a refrigerated product such as a circulating bath or a recirculating chiller is appropriate. The choice depends on a number of factors. The following guidelines help determine the type of product model best suited to one’s application.

  • Fluid operating temperature range and set-point
  • Cooling capacity (heat removal if set-point is near/below ambient)
  • Ambient temperature (affects cooling capacity)
  • Temperature stability (we offer choices from ±0.005°C to ±0.1°C)
  • External application (open or closed-loop determines pump type)
  • Reservoir size (if a bath is required)
  • Pump pressure and/or flow rate (if pumping to an external application)
  • External probe/programmability

Ambient Air Temperature

Due to air cooling, refrigerated products heavily rely on ambient air to remove heat from the refrigeration system, the ambient air temperature will affect a unit's cooling capacity. In general, while selecting a refrigerated product, decrease the product's cooling capacity rating at 1.3% for every 1° that the ambient air temperature exceeds 20°C. For instance, in case the ambient temperature where the circulator or chiller is located is 22°C, then the cooling capacity of the product will be reduced by 2.6%. At set-points close to the ambient temperature, heating products that lack refrigeration will have difficulty maintaining temperature and stability.

Circulating Bath

A typical circulating bath makes use of the ambient air to remove heat from the refrigeration system which, in turn, removes heat from the process fluid as shown in Figure 1.
