High-Quality Vertical Refrigerant Receiver Tanks
Our HVAC liquid receivers, also known as refrigeration liquid receivers or refrigerant receiver tanks, are designed to store liquid refrigerant in refrigeration and air conditioning systems. Installed after the condenser, the liquid receiver ensures that a stable supply of liquid refrigerant is delivered to the expansion device while allowing the system to operate efficiently under varying load conditions.
KAK manufactures high-quality vertical liquid receivers for commercial HVAC equipment, refrigeration systems, heat pumps, and industrial cooling applications. Our receivers are designed with durable construction, reliable sealing, and flexible connection options to meet different system requirements.
Product Overview
A liquid receiver is an essential component in refrigeration systems. It stores liquid refrigerant leaving the condenser and maintains adequate refrigerant supply to the expansion valve. During maintenance or system load changes, the receiver also provides temporary refrigerant storage, helping ensure stable system performance.
Our receivers are typically supplied in a vertical configuration, with connection ports designed for easy installation in HVAC and refrigeration equipment. Additional accessories such as sight glass, support feet, and safety valve connections can be provided depending on the application.
Main Features
- Designed for HVAC and refrigeration systems
- Stores liquid refrigerant from the condenser
- Ensures stable liquid refrigerant supply to expansion devices
- Vertical & Horizontal Configurations: While our standard vertical liquid receivers are optimized for compact equipment layouts, we also provide horizontal HVAC receivers for systems with height restrictions, such as rooftop units or under-chassis refrigeration systems.
- Multiple connection sizes available
- Optional fittings such as sight glass and safety valve connection
- PTFE sealing gasket for reliable sealing performance
- High-corrosion-resistant coating finish
- Compatible with common refrigerants and refrigeration oils
- Custom receiver sizes and configurations available
Typical Applications
- Commercial air conditioning systems
- Refrigeration condensing units
- Cold storage refrigeration systems
- Heat pump systems
- Industrial refrigeration equipment
- Water chillers
- Marine refrigeration applications
Technical Features
- Structure: Vertical liquid receiver
- Connection type: ODF copper connection
- Seal: PTFE sealing gasket
- Max allowable working pressure: 40 bar
- Burst pressure: 190 bar
- Working temperature range: -40°C to 100°C
- Compatible refrigerants: HFC, HCFC, CFC and related refrigeration oils
Installation & Orientation Flexibility
Our receiver series is engineered for versatile installation. While vertical configurations are our most popular standard, our horizontal HVAC receivers feature specialized internal dip tubes to ensure a consistent liquid seal.
This design prevents vapor bypass and ensures stable refrigerant flow even in low-profile installations or mobile refrigeration applications.
Customization Options
We provide OEM and custom manufacturing services for HVAC liquid receivers. Receiver volume, connection size, pressure rating, coating finish, and structural design can be customized according to system requirements.
- Custom receiver volume
- Custom connection sizes
- Custom pressure ratings
- Optional surface coatings
- OEM production based on drawings

FAQ
What is the function of a liquid receiver in an HVAC system?
A liquid receiver stores liquid refrigerant leaving the condenser and ensures that only liquid refrigerant enters the liquid line and expansion device. It also provides refrigerant storage during system load changes or maintenance.
What refrigerants are compatible with the liquid receiver?
Our receivers are compatible with common refrigerants such as R22, R134a, R407C, R410A, R404A, and other commonly used refrigerants together with their refrigeration oils.
What is the maximum allowable working pressure?
The maximum allowable working pressure is 40 bar with a burst pressure of 190 bar. Custom pressure ratings can be designed according to system requirements.
Are horizontal HVAC liquid receivers available?
Yes. While we specialize in vertical liquid receivers, we offer a full range of horizontal models for projects with limited vertical clearance. These are commonly used in marine refrigeration, transport cooling, and rooftop HVAC units.
All horizontal units maintain the same 40 bar working pressure rating and PED/CE compliance as our vertical series, ensuring high reliability for industrial applications.
What information is required to select a suitable liquid receiver?
To recommend a suitable model we usually need the refrigerant type, system capacity, receiver volume requirement, connection size, operating pressure, and installation space limitations.
Can the liquid receiver be customized?
Yes. Volume, dimensions, connection size, coating, and structural design can be customized according to customer specifications.
