Water Baths

Overview

Accurate Thermal Systems offers a range of Heating Circulating Systems, Refrigerated Baths and clamp on Immersion Circulators. These products cover a wide range of temperature applications from -40 to 200°C. We also offer bath fluids and thermometers for these systems. These products are a result of our 25 years of industry and application experience with water baths and temperature control systems.

The systems are broken down into three ranges, heating and circulating water baths, refrigerated circulating water baths and immersion circulators that will clamp onto an edge for use in your own bath or tank. All systems include bath lid, connection fittings, mains cable and a 2 year warranty.

Heating Circulating Baths

Heating circulating baths are designed for applications requiring more precise temperature control, accuracy and bath circulation from ambient +10ºC to 150ºC with four bath sizes to choose from.

The heating circulating baths can pump externally from the bath for temperature control of external instruments and apparatus. The system consists of an integrated controller and pump/circulator mounted over a stainless steel bath (C6 model). These systems also supports open bath applications such as sample incubation and heating as well as being a great choice for thermometer and sensor calibrations.

Refrigerated Circulating Baths

Refrigerated circulating baths are designed for both external and internal bath precision temperature control applications. The system consists of an integrated controller and pump/circulator mounted over a stainless steel Refrigerated bath. The A25 & A40 controllers have a color touch screen LCD display, adjustable high temperature cutout and low liquid level warning. Pump, heating and cooling rates are all adjustable via the LCD touch screen. There are 3 systems to choose from, two with 7 liter volume and one with 14 liter. Depending on the model they can operate from -40ºC to 200ºC all while holding ±0.010 temperature stability.

Immersion Circulator

The i-100 heating immersion circulators is an accurate and stable temperature control thermostat. The system comprises of a circulator pump and thermostat header digitally controlled via a standard display with adjustable over-temp protection. A multi-point utility clamp on the rear of the system can attach it to any container transforming it into a temperature controlled water bath. This unit is designed for internal bath circulation only. Combine an immersion circulator with a Polycarbonate bath to create your own system.

Recommended Bath Fluids

Accurate Thermal Systems offers a range of Silicone Bath Fluids for low, medium and high temperature bath applications and for both internal and external pumping.
Our low Temperature Silicone Bath Fluids are clear, colorless and odorless PDMS fluids that are characterized by their low viscosities, low viscosity-to-temperature coefficients (little viscosity change at low temperatures), low pour points, low temperature stability, chemically inert, high resistance to oxidation and compatibility with virtually all surfaces including metal, rubbers, plastics from -40 to 100ºC.

Medium Temperature Silicone Bath Fluid is clear, colorless and odorless PDMS fluids that are characterized by their high thermal stability, high resistance to oxidation, chemically inert, low vapor pressure, high flash points, high dielectric strength and compatibility with virtually all surfaces including metal, rubbers, and plastics. It covers 40 to 170ºC.

High Temperature Silicone Bath Fluid is a heat stabilized PDMS fluid that offers enhanced thermal stability and resistance to oxidation and gumming. It remains stable @ 200C in an open bath system. The fluid is a good choice for continuous use at elevated temperatures up to 200ºC.
