INTRODUCTION

 

 

1.1 DESCRIPTION OF OPERATION

The FP-4 freeze protection kit is designed to prevent aftercooler freeze up when the ambient temperature is near or below freezing, 32oF (0oC).

The FP-4 has a two stage solid state temperature controller. The controller is mounted inside a Nema 4 enclosure. The controller is used to energize a control relay which is rated to handle the load of the aftercooler fan at the various voltages.

The linear platinum temperature sensor and thermowell mount into the piping between the outlet manifold of the aftercooler and the separator. When the temperature of the com- pressed air system at the aftercooler outlet falls to 35OF, the controller will automatically turn off of the fan. The controller is set for a 10oF dead band to prevent rapid cycling (fan will turn off at 35OF and on at 45oF).

A 12 foot heat tape and 30 feet of insulation wrap are provided to wrap around the separator. The heat tape is equipped with its own internal temperature control. The heat tape and insula- tion will provide additional freeze up protection.
