PRODUCT DETAIL

The DLSB Series Chiller uses a fully enclosed compressor for mechanical refrigeration. It features cooling copper coils around the tank wall, with refrigerant (Freon) continuously circulating through these coils to cool the coolant (industrial alcohol). The built-in circulation pump and external pipeline transfer the refrigerant to jacketed reactors or condensing coils, indirectly cooling materials or liquefying vapor. It can be connected to jacketed reactors, rotovaps, and other lab equipment for low-temperature reactions.

We have models with different temperature usage ranges：
