ZT-5-200-30H Closed Refrigeration and Heating Cycle Device
A refrigeration and heating cycle device, also known as a high and low temperature integrated machine or a refrigeration and heating integrated machine, provides high and low temperature circulating liquid for cooling or heating equipment such as reaction vessels and rotary evaporators. It provides a heat or cold source for the reaction vessel through external circulation, achieving the required reaction conditions and high temperature control accuracy. Widely used in various scientific research and university laboratories such as organic synthesis, biology, pharmaceuticals, and food. There are explosion-proof types available for selection, which have the characteristics of safety, efficiency, environmental protection, and convenience.









reminder:
After the acceptance of the instrument and equipment, a one-year free warranty (excluding glass parts) and lifelong maintenance are provided.
During the warranty period of the equipment, if there are any quality problems or defects, our company will provide free replacement parts to ensure the timely and normal use of the user's equipment.
After the warranty period, if replacement parts are needed, only the cost of the parts will be charged.
