Electric Spray Booth Heater
A waterborne paint drying system with heat, manufactured in-house in the USA. Our electric heater turns a non-heated spray booth into a faster, more consistent finishing space, and we can build electric heating systems in virtually any size.
System description
The electric heater is an option for our waterborne air drying systems, built mainly for non-heated spray booths. It raises booth temperature by about 50°F.
Added heat shortens flash-off times a lot. A warmer booth during flash-off also limits how much high humidity slows waterborne paint drying.
The blower draws air from the spray booth cabin. The heating element sits in front of the blower, so air leaving the blower is heated and delivered back into the cabin through the waterborne paint drying system. Because the system recirculates cabin air instead of heating outside air, it runs very efficiently.
Cost of operation
The standard heater is a 30 kW unit. At $0.12 per kWh, one cycle costs only about $1.80 to $2.10. That is much less than a refinishing cycle in a booth heated by a gas fired unit.
System components
The system includes the following components:
- intake filter
- all ducting
- duct insulation
- 2 HP blower
- pulsing mechanism with pneumatic actuators
- 2 Slim Towers for the intake end of the booth
- 2 Original Towers with pneumatic doors for the exhaust end of the booth
- purge timer
- control panel including all interlocks required by NFPA 86
- VFD for the exhaust motor (supplied by dealer/installer)
/ Electric heater specifications
- Purpose
- Adds heat to a booth built without it. It does not replace a gas air makeup unit.
- Temperature rise
- About 50°F above ambient booth temperature
- Standard heater
- 30 kW
- Operating cost
- About $1.80 to $2.10 per cycle at $0.12 per kWh
- Blower
- 2 HP, recirculating cabin air
- Air distribution
- Pulsing towers with pneumatic actuators and doors
- Safety
- Purge timer and connection points for all required interlocks
- Control panel
- UL 508A listed, certified by ETL
Codes & standards
Built for inspection day
- NFPA 33 / IFC Chapter 24 cover spray application of flammable and combustible finishes.
- NFPA 86 / IFC Chapter 30 cover curing and drying operations.
- Full-system ETL listings are available, showing compliance with UL, NFPA and OSHA requirements. That makes permits and inspections easier than with a booth built from separately listed parts.
Requirements vary by location. Confirm details with your local authority having jurisdiction (AHJ).
FAQ
Electric spray booth heaters
When is an electric heater the right choice for a spray booth?
It suits shops without natural gas or propane service, sites with strict emissions rules, and any booth that needs clean heat without a gas line. The facility needs enough electrical capacity.
How much does the electric heater cost to run?
The standard 30 kW unit costs about $1.80 to $2.10 per cycle at $0.12 per kWh. That is much less than a refinishing cycle in a booth heated by a gas fired unit.
Does it help waterborne paint dry faster?
Yes. Raising booth temperature about 50°F during flash-off shortens drying time a lot and offsets the slowdown high humidity causes with waterborne basecoats.
How is an electric spray booth heater sized?
Sizing depends on booth size, airflow, the temperature rise you need and your cycle time. Voltage, amperage and panel capacity are reviewed during design, and we can build electric heating systems in virtually any size.
What maintenance does it need?
Routine filter changes, cleaning, and periodic checks of the fan, electrical connections, actuators and controls. With no burner or fuel train, an electric system usually needs less service than a gas heater.
