Tecumseh 51081 Refrigerant Receiver 5x9.4 in Less Rotolock

Product Description

The TECUMSEH 51081 is a refrigerant receiver designed for use in refrigeration and air conditioning systems where liquid refrigerant storage and line management are required. This receiver measures 5 inches in diameter by 9.4 inches in length and is supplied without rotolock fittings, making it compatible with installations where the technician will supply or reuse existing rotolock connections. HVAC-R technicians and refrigeration mechanics install this component as part of the liquid line assembly, typically downstream of the condenser and ahead of the expansion device.

This receiver is suited for light commercial and residential refrigeration applications. It fits into systems requiring a compact, fixed-volume liquid receiver to ensure steady refrigerant feed to the metering device and to accommodate minor refrigerant charge variations during system operation. The less-rotolock configuration referenced as 31547 indicates this unit ships without the valve port fittings installed, allowing field selection of the appropriate connection hardware.

Key Features

• Compact 5 x 9.4 inch body suited for space-constrained equipment installations
• Supplied without rotolock fittings for flexible field connection options
• Designed to hold liquid refrigerant and stabilize system charge in the liquid line
• TECUMSEH-sourced component for consistent quality in refrigeration applications

Compatibility

Designed as an OEM-style replacement or service receiver for refrigeration and air conditioning systems requiring a compact liquid receiver in the liquid line assembly. No specific model compatibility data was provided in the product input.

Installation Notes

Installation should be performed by an EPA Section 608 certified HVAC-R technician. Recover all refrigerant and depressurize the system fully before disconnecting any refrigerant lines or removing the existing receiver. Rotolock fittings and appropriate service valves must be sourced separately for this unit. Ensure the receiver is mounted in an upright, vertical orientation as is standard practice for liquid receivers unless the system design specifies otherwise.
