Copeland
The fixed capacity ZXL low temperature units come with Copeland Climate Technologies highly successful E2 Controller. The E2 controller provides real-time monitoring of compressor operating conditions and initiates actions to keep the compressor within the safe zone. When fault conditions are detected, the controller initiates temporary shutdowns and sends specific warning signals to facilitate service. In the event of continued errors, the controller will shut down the unit thereby preventing costly equipment failure and send alarm signals. ZX low temperature units applies vapour injection technology. This allows an economizer cycle on scroll compressors. Vapour injection significantly improves the low temperature operational efficiency and extends the low temperature envelope.
