Shell and Tube Dry Expansion Evaporator

Choose an upgraded shell and tube dry expansion evaporator with improved features. This evaporator ensures high performance with its thickened internal thread pipe and spiral baffle plate that creates a channeling flow within the waterway. As a result, the evaporator is now more compact and boasts elevated heat transfer efficiency - all while being compatible with any type of compressor. Get the most out of your refrigerant pipe evaporation and waterway shell refraction with this revolutionary design.
Refrigerant goes through the dry expansion heat exchange tube, while cold water runs on the outside. The efficiency of the exchanger, however, isn't very high and its coefficient of heat exchange is only around two times that of the tube heat exchanger. Nevertheless, it is quite simple to use and control, plus it requires a cooling capacity of just 1/2 to 1/3 compared to the more common flooded unit.
The dry expansion evaporator provides a reliable and efficient means of managing the air conditioning needs of any space, allowing liquid refrigerant to be quickly and effectively converted to a vapor and subsequently frozen into chilled water. This chilled water then powers the air conditioning system, ensuring optimal temperature control and comfort.
Our product line offers an impressive capacity range, with options of 12096kcal/h up to an incredible 1587600kcal/h, all customizable to your specific needs.

Request a Quote Features A vacuum environment heated and dried to high temperatures in the dry evaporator refrigerant tube eliminates all other contaminants and moisture. Utilising copper tubes of the highest grade and with a ribless construction, the dry expansion evaporator copper tube is especially resilient against corrosion and unlikely to rupture. After undergoing ultra-high pressure hydraulic or mechanical pipe rising, the fins of the dry expansion evaporator are held close to the copper tube, creating a tight seal and allowing for highly efficient heat exchange. Crafted with supreme quality steel that resists corrosion, the dry evaporator outer frame end plate is notable for its exceptional strength and straightforward assembly. To meet design flow rate needs, we've implemented both a single or a dual loop system. The internal circuit of the dry evaporator is highly efficient, with minimal water resistance and excellent heat exchange capability. Without the need for an oil return device, the lubricating oil can be returned back to the compressor. The dry expansion evaporator utilizes only one-third of the normal quantity of refrigerant, yet its cooling capacity remains the same as a flooded evaporator.
