Inteliheat HHNA/D/OR Full Height Drum Heating Jacket – 860W

When spray foam chemicals become too cold, transfer pumps work harder, pressures become inconsistent, and material flow suffers. The Inteliheat HHNA/D/OR full-height drum heating jacket helps contractors maintain stable chemical temperature throughout the entire drum, improving material consistency and reducing cold-weather processing issues.

Unlike lower-output maintenance jackets, the HHNA/D/OR uses an 860W full-height heating design for more aggressive thermal conditioning in colder environments. This makes it especially useful for contractors operating mobile spray rigs, enclosed trailers, or outdoor job sites during winter conditions.

Built for Cold-Weather Spray Foam Operations

The HHNA/D/OR wraps a larger portion of the drum surface area compared to half-height models, helping reduce temperature stratification inside the drum. By applying heat across more of the drum body, the system improves overall material uniformity and reduces viscosity fluctuations that can affect spray quality.

The jacket operates on standard 120V power and uses a fixed internal thermostat to maintain reliable material temperatures without constant adjustment.

Technical Specifications

Why Contractors Use Full-Height Drum Heaters

Cold-weather spraying often creates uneven drum temperature from top to bottom. Full-height drum heaters help reduce this issue by distributing heat across a larger surface area. Contractors commonly use the HHNA/D/OR when running spray foam rigs in colder climates where additional heating capacity is needed.

FAQs

What is the difference between the HHNA and HJNA drum heaters?

The HHNA/D/OR provides full-height coverage with higher wattage output, making it better suited for colder environments and faster overall drum conditioning.

Can this be used for polyurea materials?

Yes. The HHNA/D/OR is commonly used for polyurea, polyurethane, spray foam, resin, and industrial coating materials requiring controlled temperature maintenance.

Does this require special electrical service?

No. The HHNA/D/OR operates from standard 120V power commonly available on jobsites and spray foam rigs.
