CNG delivery | Catalytic PRS

PRS-C360

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.

Overview

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.

Two-stage regulation: control valve cut, then regulator cut, with heating ahead of each cut.

Why PRS-C360

Flame-free heating

Catalytic heating with no open flame, for compact sites, populated areas and customers who exclude fired equipment.

No separate fuel hookup

The heater runs on the process gas. Nothing else to connect.

Off-grid ready

Optional solar and battery power keeps the controls and telemetry running where there is no utility feed.

Proven on the VPT fleet

The same catalytic heating and two-stage regulation ride on NuBlu's VPT-64 and VPT-128 trailers.

Fully automated option

PLC control with remote pressure, temperature, flow and location through Ewon telemetry.

Built and tested in shop

Final assembly, FAT and loop checks happen in our shop. Issues get caught in the shop, not on your site.
