Mars sz160-4cbi 460V 3-phase Scroll Compressor

Product Description

The MARS sz160-4cbi is a Performer-series scroll compressor engineered for commercial air conditioning applications. Operating on a 460-volt, 3-phase power supply, it uses ultra-precise scroll profiles with controlled orbit to achieve oil-film sealing between scroll flanks, eliminating metal-to-metal contact and the wear that comes with it. Floating tip seals maintain axial sealing with minimal friction losses. The motor is 100% suction-gas cooled and shielded, with built-in motor protection. A large oil sump and generous internal free volume contribute to long service life and reliable operation in demanding commercial environments.

This compressor is intended for commercial air conditioning systems where 3-phase, 460-volt power is available. Its compact footprint and optimized discharge assembly make it suitable for rooftop units, split systems, and packaged equipment where low noise and reduced vibration are operating requirements. Installation and service are typically performed by licensed HVAC technicians working on light commercial or commercial refrigeration and cooling systems.

Key Features

• Ultra-precise scroll profiles with oil-film sealing eliminate contact between scroll flanks, reducing wear
• Floating tip seals provide axial sealing with low friction losses
• 100% suction-gas cooled and shielded motor with built-in motor protection
• Large oil sump and large internal free volume for extended reliability and service life
• Optimized discharge assembly for reduced noise and improved efficiency

Compatibility

Designed as an OEM-style replacement or new-installation scroll compressor for commercial air conditioning systems operating on 460-volt, 3-phase power.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with applicable mechanical codes and EPA Section 608 refrigerant handling regulations. Disconnect and lock out all electrical power and recover refrigerant from the system before removing the existing compressor. Verify oil type and charge requirements match system specifications before startup. Do not energize the compressor before confirming correct wiring, refrigerant charge, and oil level.
