Description
Pilot Gas Heater
Bruest Catalytic Heaters’ Freez-Fiters pilot gas heaters safely and effectively heat low volumes of gas used by pilot regulators and instruments.
The gas travels through the heat exchange coil to be heated by the infrared heat. The heater’s gas train includes all the necessary instruments to operate.
Optional temperature controller allows the heater to modulate the heat output to fit the demand of the application. The dual coil option adds a second heat exchange coil.
This secondary coil can either be used to supply gas to a second pilot regulator or be used in series with the primary coil.
Custom configurations allow the Freez-Fiter pilot gas heater to be used in wide ranging applications.
Specifications - Pilot Gas Heater
The Freez-Fiter family of heaters operates on the same principle as all of Bruest’s Catalytic Heaters.
A power supply source is required to preheat the catalytic pads. Power is applied for 15 to 20 minutes before the fuel gas is introduced.
The power can be removed 10 to 15 minutes after gas valve has been opened.
Power is not required during normal operation. The Freez-Fiter can be shut off by turning off the fuel gas supply.
Fuel Gas Heater
Bruest Catalytic Freez-Fiter Fuel Gas Heaters were designed to heat low to medium volume of gas with one or more catalytic heater panels to heat a serpentine process gas coil.
The Freez-Fiter family of heaters is offered with high pressure regulators to reduce the inlet gas pressure to the fuel gas train, an integral filter to remove contaminants, and temperature controllers to adjust the temperature of the process gas.
Bruest’s Freez-Fiter family of fuel gas heaters are great alternatives to larger fuel gas systems.
Specifications - Fuel Gas Heater
The Freez-Fiter family of heaters operates on the same principle as all of Bruest’s Catalytic Heaters.
An electric source is required to warm up the catalytic pad.
Once the pads are warmed up, which should take between 15 to 20 minutes, the electric supply can be removed and the gas supply takes over.
After the gas is introduced, the catalytic reaction will supply the necessary heat to continue the process.

Why Choose the Bruest Freez-Fiter Pilot Heater
Why Choose the Bruest Freez-Fiter Pilot Heater
Value Elements
- Reliable Freeze Protection for Pilot and Instrument Gas
- The Freez-Fiter is designed to heat low-volume gas streams used by pilot regulators, controllers, and instruments, helping prevent freeze-ups caused by pressure drops, cold ambient conditions, or moisture in the gas stream.
- Flameless Catalytic Heating Technology
- Using Bruest’s catalytic heater technology, the Freez-Fiter delivers infrared heat without an open flame, making it well suited for natural gas applications and hazardous-location installations where safe, dependable heat is critical.
- Efficient Operation with Minimal Power Requirements
- Power is only required during startup to preheat the catalytic pads. Once operating, the catalytic reaction maintains heat output, so the unit does not require continuous electrical power during normal operation.
- Compact, Lightweight, and Easy to Install
- The Freez-Fiter’s compact design makes it a strong fit for new builds, retrofits, and tight station layouts where larger heating systems may be impractical or costly to install.
- Flexible Configuration Options
- With options such as temperature control, single or dual coils, multiple tubing sizes, and different startup voltage options, the Freez-Fiter can be configured for a wide range of pilot gas, instrument gas, and low-flow fuel gas heating applications.
- Low-Maintenance Construction
- With stainless steel construction, no moving parts, and no costly heat transfer medium to fill or maintain, the Freez-Fiter is built for long-term operation with minimal maintenance requirements.
Comparison vs. Next Best Alternative
- No Continuous Power Requirement
- Compared to electric pilot gas heaters, the Freez-Fiter only needs power for startup. Once the catalytic pads are heated and fuel gas is introduced, it can continue operating without ongoing electrical power.
- Simpler Than Larger Fuel Gas Heating Systems
- For low-volume pilot gas, instrument gas, or small fuel gas applications, the Freez-Fiter offers a compact alternative to larger, more complex heating systems.
- Direct Heating Without Heat Transfer Fluids
- Unlike systems that rely on a heat exchange medium, the Freez-Fiter heats the process coil directly. That means no fluid to fill, no spill risk, and fewer maintenance concerns.
- Built for Hazardous and Remote Installations
- With available hazardous-location classifications and startup options including 12 VDC, 120 VAC, or 240 VAC, the Freez-Fiter is well suited for remote regulating stations, metering sites, and field installations where power availability may be limited.
- Flexible Across Multiple Low-Flow Applications
- While many alternatives are focused mainly on pilot regulator freeze protection, the Freez-Fiter can also support instrument gas heating, fuel gas heating, CNG regulation stations, standby generator fuel gas heating, and custom low-volume gas heating applications.
Where Do I Use This Product and Why?
- Pilot-Operated Regulator Stations
- Use the Freez-Fiter where pilot supply gas needs to stay warm and reliable. It helps prevent freezing in pilot lines so regulators can continue operating consistently in cold weather or high-pressure-drop conditions.
- Instrument Gas and Control Lines
- Ideal for heating low-volume gas streams feeding controllers, pilots, and instrument regulators where freeze protection is essential to reliable system performance.
- Small Regulation and Metering Stations
- The Freez-Fiter is a strong fit for smaller station applications where a full-size fuel gas heater may be oversized, too expensive, or difficult to install.
- Remote or Retrofit Installations
- Its compact footprint, low maintenance requirements, and startup power flexibility make it practical for remote sites or retrofit projects where installation space and power infrastructure are limited.
- Low-Volume Fuel Gas Heating Applications
- In addition to pilot gas heating, larger Freez-Fiter models can be used for low to medium volume fuel gas applications, including CNG decompression, LPG vaporization, glycol heating, standby generator fuel gas heating, and custom instrument gas heating.
