Introduction:
The MVP Clean Flow Heater (CFH) is designed to allow higher flow rates, give better
control over temperature change and boasts a new easy maintenance design.
The CFH-4000 Heater is heated with a single 3000 watt cartridge type heating element,
requiring 240 Volt, single phase electrical service at 15 amps. Material temperature is
indicated on the thermometer on the outlet side of the heater.
The bulb and capillary thermostat has a fluid filled bulb. When temperature rises, the
bulb fluid expands via a capillary tube to an expandable diaphragm within the remote
thermostat case activating an electrical switch at the thermostat set point. Designed to
maintain a constant and stable temperature, these devices offer precise heating control.
There is also a thermal limiter in the circuit. This is a safety feature that breaks the circuit
to the heating element if heater block temperature exceeds a safe level. In addition, all
heaters contain 15 amp fuses in the electrical enclosure for protection.
There are a couple of models of the CFH-4000 in-line resin heater:
3000 Watts, 1PH, 220vac @ 13.63amp
CFH-4000-B
Basic Clean Flow Heater – In-Line Resin Heater
CFH-4000-AI Clean Flow Heater – In-Line Resin Heater – Air Interlock
CFH-4000-AIDS Double Stack – In-line Resin Heaters
The CFH-4000-B Basic Clean Flow Heater is the base model of the CFH heater with a
single temperature adjustment knob which allows for simple operation. Just adjust the
temperature control to the desired level to maintain the desired temperature indicated
on the thermometer.
The CFH-4000-AI Clean Flow Heater – Air Interlock is unique in that it is an on demand
type heater and uses electrical power only when there is flow. The heater is controlled
by triggering the gun, the system regulator supplies pressure to the gun valve which in
turn activates the heater when the trigger is pulled. Once material is flowing, an air
signal is supplied to heater which engages the thermostat circuit.
When controlled with the air/electrical interlock heater switch, The CFH heaters require
a minimum of 15 psi air. The heat element is supplied with current from two separate air
circuits: the preheat circuit and gun trigger circuit. A preheat circuit is operated to
manually warm the heater block to desired operating temperature before start-up.
The CFH-5000 Clean Flow Heater – is a 4000 watt, 1PH, 220Vac @ 18.18amp inline
heater configured for a remote control box. The CFH-5000 Heater features a 1/2” NPT
resin inlet and outlet port and a thermocouple port for sensing the temperature remotely.
The CFH-5000 Heater also has a 1/2” NPS port used for electrical connections to the
heater element. The CFH-5000 Heater will assemble and disassemble the same as the
CFH-4000 Resin heaters and will have the same maintenance and safety requirements.
