Low Temperature Coolant Circulation Pump

DLSB50-30 Cooling Chiller

The DLSB series of low-temperature coolant circulation pumps are a type of equipment mainly used by ZZKD laboratory equipment manufacturers for condensation and refrigeration. This cooling chiller has the characteristics of fast cooling speed, corrosion resistance, and simple operation.


- With the microcomputer software lock function, it can lock the system parameter settings.
- All operations are performed by pressing the touch soft key on the microcomputer intelligent controller, which is easy to operate.
- The circulatory system is made of anti-corrosion material and has functions such as anti-rust, anti-corrosion, and low-temperature liquid pollution sterilization.
- Under the conditions of water shortage, poor water quality, high water pressure and high temperature, it can effectively guarantee the normal use of various precision instruments;
- The unit combines circulation and cooling to save more space.

1. Features unique to the DLSB chiller.

All parts that come in contact with liquid are made of stainless steel, which is resistant to corrosion, rust and cold.Magnetic stirring at the bottom can drive the magnetic stirring in the tank to make the temperature completely uniform, increase the distance between the stirring magnet and the stirring rod, and increase the stirring force.

2. I have a 20l rotary evaporator. How should I choose a low-temperature circulation pump?

20L rotary evaporator equipment, you can choose DLSB-20/30 or DLSB-20/40 coolant circulation pump. The capacity is 20L enough, and the temperature needs to be chosen according to your actual situation.

3. How will you delivery these goods?

It will be decided according to your quantity. Normally we will choose International Express, Air and sea.
