PRS-G series
Glycol bath heater. High-volume, continuous duty with reliable heating.

A compact, flame-free pressure reduction system for mid-size and smaller loads. A catalytic heater puts the heat back into the gas without an open flame, two-stage regulation takes trailer pressure to site pressure, and the package runs unattended on optional solar and battery power.
The PRS-C360 is built for sites that need up to 360 MSCF/d of regulated gas from CNG trailers without a fired heater. A catalytic heater produces heat through a flameless reaction on a catalyst pad, which suits compact sites, populated areas and locations without a separate fuel hookup.
Two-stage pressure regulation with heating ahead of the cuts holds the gas above freeze conditions as it drops from trailer pressure to site pressure. The package is the same regulation and heating design carried on NuBlu's VPT virtual pipeline trailers, packaged as a standalone skid.

| Design standards | ASME Section VIII Div. 1, B31.3, NEC, NFPA |
Flow capacity, outlet pressure and heater sizing are confirmed to your inlet pressure, gas composition and site conditions. Contact engineering for a sized proposal.
Catalytic heating with no open flame, for compact sites, populated areas and customers who exclude fired equipment.
The heater runs on the process gas. Nothing else to connect.
Optional solar and battery power keeps the controls and telemetry running where there is no utility feed.
The same catalytic heating and two-stage regulation ride on NuBlu's VPT-64 and VPT-128 trailers.
PLC control with remote pressure, temperature, flow and location through Ewon telemetry.
Final assembly, FAT and loop checks happen in our shop. Issues get caught in the shop, not on your site.
Every PRS ships with a complete engineering package: P&IDs, GA drawings and an O&M manual. Critical spares are stocked at our shop for fast response.
Field service, troubleshooting and remote diagnostics are handled by the same team that designed and built the unit.
