About refrigerated bath circulators

Refrigerated bath circulators control processes below and above ambient temperature. Required cooling capacity depends not only on the set point, but also on heat load, fluid, ambient conditions, bath volume and connected equipment.

Suitable applications

  • Sample and reagent temperature control: stable conditions for preparation, incubation or testing.
  • Instrument and process support: circulating fluid to a compatible external load.
  • Research and quality control: repeatable settings and documented checks where required.

Selection criteria

  • Temperature range: include ambient conditions, heat load and required pull-down or heat-up time.
  • Stability and uniformity: distinguish controller accuracy from performance in the actual load.
  • Pump and connections: match pressure, flow, hose, fittings and elevation difference.
  • Bath and fluid: verify volume, material, viscosity, flash point and compatibility throughout the range.

Configuration and safe use

The selected heat-transfer fluid, tubing and vessel must be suitable for the entire operating range. Provide adequate ventilation and prevent condensation, overflow, dry running and contact with hot or cold surfaces. Cooling or heating capacity must be assessed at the required operating temperature, not only at the headline maximum.

Advice, delivery and service

Poly Temp Scientific helps translate the application into a complete, compatible configuration. We check the main product, required options and accessories and can coordinate delivery, commissioning and service. Product specifications and your local risk assessment or ergonomic protocol remain decisive.

Frequently asked questions

How do I choose the correct model?

Start with the actual process, load, vessel or user, required range and environment. Then compare capacity, adjustment, control and accessories. Poly Temp can check the complete configuration.

Are all accessories interchangeable?

No. Platforms, clamps, probes, hoses, castors and other accessories can be model- or configuration-specific. Confirm compatibility by exact product and option code.

Can I request a customised configuration?

Yes. Many products offer options for capacity, control, holders, materials, height or accessories. Poly Temp checks feasibility and records the selected configuration in the quotation.

What should I provide for advice?

Provide the application, required performance, samples or vessels, expected load, available space, utilities and any hygiene, ESD, safety or documentation requirements.

Does Poly Temp provide service?

Yes. Depending on the product, Poly Temp can provide delivery, commissioning, user instruction, preventive maintenance, calibration or repair. The scope is agreed in advance.
