Heatcraft Refrigeration 5709L Chandler defrost termination fan delay thermostat

35F-Cls 55F-Opn DEFROST LIMIT

This termination delay thermostat can be used with any Heatcraft 35F-Cls or 55F-Opn Series canister coil. It provides delay in terminating the refrigeration cycle after the evaporator coil cools down to 35F, and turns it into heating mode at 55F. This feature allows time to drain off any moisture that might accumulate, reducing the chance of rusting when moisture is heated on the cold evaporator coil

The 5709L is a defrost termination fan delay thermostat that opens the de- frost heat relay at 55F and closes the relay when returning to 35F or less. This thermostat will delay the defrost cycle, thus allowing more time for dirt and frost to accumulate on the outdoor coil.

Zero-power to a defrost termination fan delay thermostat designed to initiate a defrost cycle based on a thermal limit control. The body has an axial leaded type terminal arrangement with a 15-pin D type connector providing terminal positions 1 and 9. The CD35F & CD55F are snap mounted, unlatched single pole snap switches manufactured using high reliable, small form factor LRA (Lightning-Resistant Alloy) for exceptionally low resistance and low contact resistance, which ensures minimal power consumption and superior short circuit protection. Also available in IP23 rated version with two additional terminals at the end of the

The Heatcraft Refrigeration 5709L Chandler defrost termination fan delay thermostat is designed to control refrigeration units like those found in restaurants, grocery stores, or other similar areas for short periods of time. This thermostat has a low-limit temperature of 35°F and an upper-limit temperature of 55. Fahrenheit and is designed for use with refrigerant systems operating from 35F to 55F .

This product is in the Refrigeration Systems & Equipment industry, which is a heavyweight industry in the Commercial Refrigeration sector. This product is a Chandler Defrost Termination Fan Delay Thermostat, an application that requires some technical knowledge.

The 5709L is a Temperature Limiting Device (temperature control) which controls the ON/OFF cycling of the defrost termination fans upon a call for defrost from the control. The 5709L can be used on new installations or on existing installations that have multiple defrost termination fan sections controlled by independent defrost heating circuit boards.

A single speed, non-adjustable thermostat used to control the fan on a defrost termination. Features include automatic reset, high limit amp rating and grounded neutral. Designed for use in defrost applications.
