Description
The Refrigeration Bath Circulators are created to control the temperature of externally connected. Applications are: photometers, refractometers, viscometers, double-jacketed reaction vessels and autoclaves. the units can be used, for determining the freezing point, for deep temperature calibration, for petroleum tests, for temperature control of measuring devices and experimental setups as well as for materials testing and quality control.

Frequently asked questions
How does the two-stage refrigeration circuit work here?+
The unit uses a cascade: a first stage charged with 0.78 kg of R452A and a second stage charged with 0.46 kg of R508B. Both are classified A1 (non-flammable) under ASHRAE. The cascade is what allows a −90 °C bath temperature from an air-cooled machine.
What cooling capacity is available across the range?+
The data sheet gives 1.2 kW at 100 °C, 20 °C and 0 °C, 1.1 kW at −20 °C, 0.9 kW at −40 °C, 0.6 kW at −60 °C and 0.2 kW at −80 °C. Heating capacity is 1.2 kW.
How large is the bath?+
Bath volume is 5 litres, with an opening of 120 × 110 mm and a usable depth of 150 mm (4.72 × 4.33 in, 5.91 in deep). It is a small bath for the machine size — most of the footprint is the cascade refrigeration plant.
What are the electrical and space requirements?+
208 V 2~ 60 Hz, drawing a maximum of 18 A with 2 × 20 A fusing. The unit measures 550 × 600 × 911 mm (21.65 × 23.62 × 35.87 in) and weighs 139 kg (306.5 lb), so a bench check is worth doing before delivery.
What pump performance does it provide?+
25 lpm at 0.7 bar in pressure mode and 18.5 lpm at 0.4 bar in suction mode, through M16x1 male connections, with a permissible fluid viscosity of 50 mm²/s. Note that thermofluid selection matters at −90 °C: viscosity at the low end of the range governs achievable flow.
What controller does it use?+
Pilot ONE at E-grade "Basic" with a 5.7 in colour touchscreen, Pt100 external probe connection, and RS232, Ethernet, USB Device and USB Host interfaces for remote control or data capture.
