Unitized Heaters remain Process Heating Company's best selling product line. Its popularity continues due to the ease of installation into any tank or vat; its 100% efficiency; its ease of automation; its lack of maintenance and remarkable reliability. The “Lo-Density” Unitized Heater dissipates as low as three watts per square inch on the heater sheath. The PHCo Unitized Heater is viable with most temperature sensitive products for most every industry; asphalt and other petroleum derivatives for reducing viscosity; animal oils, fats, molasses for food production; lignite's, waxes, paints, inks, etc.

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.

With over 50 years experience in the manufacturing business, PHCo has emerged as the builder of the highest quality Hot Oil Heat Transfer systems in the industry. These units use LO-DENSITY® 100% efficient patented Coil-Lock design heating elements which will eliminate any coking or carbonization of your transfer fluid. PHCo's system will provide automatically controlled, even temperature transfer fluid for industrial process equipment such as jacketed lines, pug mills, weigh buckets, jacketed pumps, industrial dryers, production platens, and many other industrial and commercial applications.

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.

PHCo's "Lo-Density"® Circulation Heaters are perfect for in-line heating of fluids. These are complete packaged systems available with or without control panels. The Flanged vessels are available with ASME pressure rating and include high temperature insulation and weatherproof aluminum jacketing. The heating elements are low watt density, under 10 watts per square inch to reduce fouling in viscous products. The "dry well" design elements can be removed for service without interrupting your process, a distinct advantage. The terminal enclosures are weatherproof as standard and available for hazardous environments in some sizes.

PHCo's "Lo-Density"® electric preheater is the solution if you are looking to save dollars when using the heavier or reclaimed fuel oils. PHCo has developed, through years of research, a system to increase atomization, insure smoother flow, have a more accurate control of temperature and improve combustion. PHCo preheaters are perfect for steam boilers, aggregate dryers or other large burner operations. PHCo preheaters are available in a wide variety of sizes to pinpoint the exact requirements and to accommodate a burner in any climate. All PHCo preheaters include a prewired U.L. Listed Industrial Control Panel.

Heavier oils move smoothly to the burner with PHCo's in-line electric preheater. Now offered with removable tubes to facilitate cleaning. This system beats the viscosity barrier! If you are converting your plant to heavier fuels, viscosity control must be addressed. Nothing is simpler, nor more cost-efficient, than Process Heating Company's Lo-Density® in-line preheater. It picks up between the pump and the burner nozzle to assure the efficient delivery of a steady flow of fuel to the burner at proper temperatures.

Flanged Immersion Heaters for use in tanks, large vats and reservoirs. These heaters consist of a standard 150# or 300# flange for mounting and PHCo’s exclusive heating elements. The elements are "dry well" and "low density" design. The dry wells allow the elements to be serviced or replaced without draining the tank. The low watt density design keeps the element sheath temperature low. The heaters can be supplied either with or without our custom, U.L. Listed industrial control panels. PHCo offers many advantages over traditional style tubular elements.

The PHCo "Pump-in-Box" is offered two ways. Both systems are heated to assure the pump and valves are always at the correct temperature and ready to operate. The complete assembly consists of either a gear reduction, or a direct-driven/positive displacement gear pump and valves, with heavy duty electric motor - all mounted on a common base which in turn is heated. The base-mounted driving motor is located outside the heated enclosure, away from the heat zone.

Rigid Tubular Drywell Heaters solve the problem of heating viscous products without damage to the product being heated. The Rigid Heaters can be installed as new or as replacement equipment for existing metal sheathed style tubular units that have higher watt density. Process Heating’s Rigid Heaters ease maintenance with their drywell design, allowing replacement without draining the reservoir, resulting in no machine downtime. The low watt density design reduces damage to the material being heated and build-up on the elements, resulting in longer heater life.

Only heat your product when needed. Apply energy to liquids as they are being drawn from storage tanks. Sizes available up to 600 kW. Reduce energy consumption. Reduce or eliminate storage tank maintenance heating. 100% of the energy consumed goes into your product when needed. Simple installation. Cut a round opening in the tank head or sidewall, install heater assembly and weld liquid tight. The U.L. Listed control panel is factory mounted and wired to the heaters. Pinpoint heating puts energy where it is needed with no wasted energy. Electric heat is 100% efficient during the life of the heater.

Heater elements are readily available in lengths from two feet to forty feet and can be custom sized to match both heating requirements and tank dimensions. Single and three-phase elements can be furnished. Elements are constructed of nickel chromium alloy coils that are supported by patented ceramic insulators. Elements can be flexed to a minimum radius of 24" for insertion in confined areas.

Patch King provides trouble free asphalt patching capable of heating your patch mix effortlessly without hot or cold spots. No propane or open flame on public streets. Heats cold mix to a more workable temperature. Has timeclock for early morning pre-heating. Uses safe, clean, reliable electric heat. Just plug it in. U.L. Listed controls are the brains of the Patch King.

The reversible rotary conveyor is driven by a hydraulic motor and supported by heavy-duty ball bearings. A mix/anti-bridging device features separate hydraulic drive and controls. The wear parts, including auger and trough, are easily replaceable. Reversible auger feeds patch mix to work area to eliminate costly dump beds and hoists.

Now Process Heating Company introduces the all new trailer mounted Patch King that can go anywhere, anytime. This is our first trailer mounted version using electric heat. The PK30T model has most of the benefits of the standard model including: automatic control, meaning it can hold unused mix overnight for use the next day; it can be hitched to your truck and ready to go in minutes; the thermostat control will hold cold or hot mix from 50 - 350 degrees.

Process Heating is going "underground" Process Heating's Problem Solving: The HMAs are first in line as Process Heating Company introduces a major advancement in underground tank heater technology. It starts at the top. The SWEEP system inserts at the TOP of the below-ground tank. The Lo-Density electric elements sweep down from the top for maximum control and efficiency. Maintenance and replacement are from the top. No need to send personnel into the tank. Heavy duty savings result from easy topside access, cost-effective Lo-Density technology, and automatic controls that take advantage of low off-peak power rates.

The "Problem Solver" for underground tanks. Having trouble solving your underground storage tank problems? PHCo “Lo-Density”® Drop-In Heater Kits have been designed for the heating of underground tanks and other applications that cannot be cut or welded on. These heaters can be used in multiples if needed and laid on the tank bottom end to end, appropriately spaced with varying lengths and flexible power leads supplied by PHCo.
