Engineered Low Pressure Ammonia Vessels
Refman Engineering Equipments Pvt. Ltd. manufactures high-performance Ammonia Low Pressure Vessels including Accumulators and Surge Vessels to ensure optimum refrigerant control and system stability across industrial refrigeration systems. Our vessels are engineered for safety, efficiency, and long-term durability, serving industries like cold storage, seafood, dairy, chemicals, pharma, and food & beverages. Built to comply with modern engineering standards, our solutions offer precise refrigerant flow control in large ammonia refrigeration systems.
Types of Ammonia Low Pressure Vessels
Ammonia Accumulator
- Balances refrigerant flow by collecting surplus liquid ammonia and separating it from vapor.
- Prevents compressor damage due to liquid slugging.
- Designed for stable system operation even under fluctuating load conditions.
- Supports both flooded and DX-type evaporator systems.
Ammonia Surge Drum / Surge Vessel
- Collects and distributes liquid refrigerant to evaporators ensuring equal flow.
- Helps maintain constant pressure and ensures proper return of vapor to the compressor.
- Ideal for multi-evaporator systems requiring precise liquid levels.
- Available in various MOC: Galvanized Steel, SS304, SS316 based on application need.
