HHP Hydronic High Performance Heater
The HHP series of heat-exchanger unit heaters is designed for the most rugged industrial applications in steam, hot water, glycol or other fluid circulating heating systems. The HHP series is designed for pressures and temperatures up to 450 psi and 550 °F respectively. HHP heaters include our PerformaCore™ high-performance heat-exchanger cores that are available in 5/8 in. O.D. 16-gauge (0.065 in.) fin tube with single-pass (for steam or fluids) and multi-pass configurations (for fluids only) to meet your specific requirements. HHP heaters meet ASME requirements with a CRN.
HHP Data Section
The Hydronic High Performance (HHP) series of heat-exchanger unit heaters is designed to meet the most demanding requirements of heavy industry. The harsh operating conditions of this industry require heating equipment that is safe, reliable, dependable, and available when you need it. The rugged design features of the HHP series also makes it ideal for use in heavy-duty industries that include oil & gas, pulp & paper, power generation, mining, steel mills, foundries, water and wastewater treatment plants, chemical plants, and hazardous material storage facilities.
Designed for operating pressures up to 450 PSIG (3103 kPa)!
All All Hazloc Heaters™ HHP models are designed to ASME requirements for applications with maximum operating pressures up to 450 PSIG (3103 kPa). The four sizes of HHP heaters include our PerformaCore™ high-performance heat-exchanger cores that are available in 12 model choices of 5/8 in. O.D. fin tube with single-pass (for steam or fluids) and multi-pass configurations (for fluids only) to meet your specific requirements.
HHP heaters are suitable for a wide variety of heating fluids and are perfect for steam, hot water, or glycol applications. They are also used with other non-lethal or non-poisonous fluids (as defined by ASME) for both space heating and liquid cooling applications that include but are not limited to hot-oil heaters, lube-oil coolers, product process coolers, pumpseal coolers, etc.
Rugged design, but easily maintained!
All HHP heaters are designed for industrial applications with all features being heavy-duty to meet your most demanding environments and long-life expectations. Even with heavy-gauge steel construction used throughout the heater it does not inhibit maintenance of the product since all cabinet panels are easily removed.
Interchangeable with other brands of heaters!
Hazloc Heaters™ HHP series are designed with cabinet dimensions and mounting holes equivalent to a major competitor’s heaters making them easily interchangeable. Furthermore, our rugged and superior HHP PerformaCore™ replacement cores are also designed to slide into equivalent sizes of their heaters. An added benefit is our 18-month heater warranty!
Maximum durability… rugged fin tubes and headers!
All HHP PerformaCore™ heat-exchanger cores are constructed using rugged 16-gauge (0.065 in.) carbon-steel tubes with tension-wound aluminum fins and carbon steel headers for maximum durability, resistance to corrosion, and longer life in your demanding applications.
Take advantage of our proprietary heater sizing and selection program!
Hazloc Heaters™ has developed a web-based heater sizing and selection program that will assist you with estimating your building’s heating load and in selecting the right HHP series of heater for your application. Our software computes performance parameters under a diverse range of operating conditions.
Hazloc Heaters™ ACOL heater selection tool is capable of rating heaters for steam, or for fluids based on either the flow-rate or temperature-drop sizing methods. Our software is also pre-programmed with the following fluid types for quick and easy analysis.
Steam
Water
Ethylene Glycol/Water
Diethylene Glycol/Water
Therminol 66
Triethylene Glycol/Water
Dowtherm A
Dowtherm G
and others...
Once you know your heating load, all you require is the following input data!
• Type of fluid used
• Operating pressure
• Inlet fluid temperature
(liquid applications only)
• Outlet fluid temperature, or available fluid flow rate
• Altitude above sea level (ASL)
• Entering air temperature
If your fluid isn’t listed above, we can still help!
You can still size our heaters using other fluids not listed above by manually inputting the following fluid physical properties: Temperature, Density, Specific Heat, Thermal Conductivity, and Viscosity at two reference points.
This brochure was produced using Imperial units of measure. If required we can provide you with data in Metric units.
• † Other finned tubing options available for custom order. Contact factory.
• ^ 2" 300# ANSI blind RF flange with 1-1/2" dia. hole machined in center
(eight 3/4" bolt holes).
• ‡ Contact factory for extended shipping lead times on Heresite coated cores.
• * Other voltages available upon request. Longer lead times may apply. Contact factory.
• Motors are designed to be operated at rated voltage with tolerances of ± 15%.
• If ordering explosion-proof motor, ensure equipment meets the requirements of your hazardous area rating.
