PHCo Product Overview
Our Heaters are specifically designed to heat the products others don't want to talk about.  Products like asphalt, light and heavy fuel oils, diesel, bio-diesel, glycerin, lube oils, hydraulic fluids, resins/epoxies, animal fats, molasses and other materials that are sensitive to high temperatures.  Our exclusive LO-DENSITY®, low watt density design spread the heat out over large surface area eliminating high element temperatures that damage products.  All of our systems utilize drywell type heaters with open coil element assemblies that can be removed and serviced without draining tanks or systems, eliminating down time.  We have been building all electric, clean, safe and 100% efficient systems since 1947 and have the experience it takes to provide you with the best heating solution for your tough applications.

No tanks to drain. Easily installed the heavy-duty assemblies weld directly into storage tanks to deliver long term and economical performance. Once installed, the flexible heater elements are removable from heater tubes without the need to drain the tank or disconnect fluid lines. LO-DENSITY® IS A BIG PLUS. The large heater surface area is designed with a pre-determined low watt density (watts/sq. in.) giving low sheath temperatures to avoid coking or damage to the material being heated.

All-In-One Heater Kit
This remarkable Heater Kit can be used for heating an asphalt tank and supplying hot oil for the plant. Maintaining asphalt at desired temperatures is a primary feature of this new PHCo heating system. In addition it circulates oil through scavenger coils and over thermostat controlled electric booster heating elements. This provides hot oil for heating of jacketed lines, pumps and valves, drags, silo cones and plant components. The scavenger coils allow for quick heat up while booster coils elevate oil temperatures above the asphalt storage temperature if higher temperature hot oil is required.
