A Thermal Liquid Heater
Designed And Built Like No Other

Designed with simplicity, efficiency and safety in mind.

Our Parker bent steel liquid tube design offers an extremely efficient, reliable thermal fluid heater built for the long term and ease of maintenance. Low NOx burners are available.

Parker Direct Fired Type Heaters represent an ideal heating system for thermal liquids. Our, all double welded bent steel liquid tube design allows for the continuous expansion and contraction to which the heater must be subjected without damage.

Process heating applications which require temperatures between 350° and 650°F can frequently be serviced more dependably, efficiently, uniformly and safely with a Thermal Liquid System.

sealed combustion design

Our Thermal Liquid Heater is also designed with a sealed combustion chamber. See our 207WW Series. Low NOx Models Available!

What Is Thermal Liquid Heating

Thermal Liquid Heating is a specialized form of process heating that utilizes the forced circulation of special heating medium as a liquid. In many types of process heating, high temperature, rather than high pressure, is essential where heat, not vapor or steam per se, is required.

Thermal Liquid Systems can generally be used at high temperature without a corresponding high pressure.

PERFORMANCE

BTU Inputs Up To 6,250,000
Temperatures Over 650°F
Gas, Power Gas, Oil or Combination Fired

Thermal Liquid FLuids

Fire resistance, cold flow and freeze points, high operating temperatures, viscosity at varying temperatures, life expectancy, vapor pressure characteristics, and of course, fluid cost are among the deciding factors in fluid selection.

Heavy Duty Pumps

In closed recirculating Hot Water Systems, pump selection in GPM is based on the desired temperature rise through the heater and the system head pressure.

Parker Designed Tanks

Selection of the system expansion tank can generally be based on the simple formula of 4% expansion per 100°F of temperature.

A Closer Look Inside
Low NOx Premix Technology

The Parker liquid tube design offers an extremely efficient, reliable heater built for the long term with ease of maintenance. The Parker design offers many advantages. Compare ours to the competition. The staggered tubing design provides a 10-pass self-baffled heating surface to increase efficiency. Our ASME tube bundle is extremely flexible and offers a long life with a 25 year warranty against thermal shock. No Parker Boiler has ever been known to experience an internal explosion.

Advantages to having a Low NOx Boiler

• Parker heavy duty premix metal fiber burners.
• Burners provide the lowest emissions possible with a long durable service life.
• Variable Speed Blowers for electrical energy savings.
• Fully modulating variable speed Low NOx Burner Systems offer many advantages.
• Lower Low NOx & CO levels are attained by our Premix Burner System.

Thermal Liquid Heating is a specialized form of process heating that utilizes the forced circulation of special heating medium as a liquid. In many types of process heating, high temperature, rather than high pressure, is essential where heat, not vapor or steam per se, is required. Thermal Liquid Systems can generally be used at high temperature without a corresponding high pressure.

The Parker Direct Fired Type Heater represents an ideal heater for Thermal Liquids. Our all welded, bent steel tube design allows for the continuous expansion and contraction to which the heater must be subjected without damage. Please refer to our Brochure 207 for internal construction details. The double welded construction eliminates the problems of rolled or poor joining of tubes, experienced in competitive units. This type of heater is preferred by more Fluid Manufacturers.

 

Advanced Temperatures

Thermal Liquids at advanced temperatures are so thin that only the finest welding can contain the fluid without leakage. Since all fluids will burn in the ambient temperature of the gas flame, this leakage can be serious with other than our design. The effects of thermal liquid shock are nullified in our serpentine design tube assemblies.

Types of Applications

• Chemical Plants
• Plastic Molding
• Cooking Fish Sticks To Potatoes
• Asphalt Heating
• Laundries
• Wood Veneer Manufacturing
• Particle Board Pressing
• Soil Remediation
• Food Processing
• Oil Heating
• Adhesive Heating

CONTROLLED FLOW

With the optional weather protective cover our boilers can be installed in an outdoor area. This is accomplished with baffles in the upper and lower headers directing the flow through a selected number of tubes in each pass.

DURABLE CABINET

The cabinet is specifically designed and constructed for high temperature service using reinforced sheet steel effectively insulated to retain heat within the cabinet. The exterior is protected with a baked enamel finish.
