Constructional features

Turbulence reduced five-speed duplex pump and built-in cooling coil let you use in an open or closed
bath environment (1 to 3 steps of pump for internal circulation / 4 and 5 steps for external circulation)

Baffle plate screens circulator, heater, and sensor to minimize turbulence in the bath fluids and to protect
the samples and user from direct contact with the heating or cooling element.

Dry-running protection; automated heating element cut-off and audible and visual warning.

Seamless stainless steel tank with a reservoir drain that resists corrosion and make cleaning easy.

Use CFC-free refrigerant R-134A, R-404A and double service valve to prevent the leakage of refrigerant.
