Powrmatic CX Warm Air Cabinet Heater Range offers ultra-low NOx G20 heating 30–300kW with upright, horizontal or external options for industrial sites. Proven. The Powrmatic CX range is a cabinet-type warm air heater platform designed for commercial and industrial buildings that need dependable heat delivery, sensible service access, and compliance-ready emissions performance. In plain terms: it’s a “big space” heater range that’s happy in a plant room, on a wall line, or even outside (EA models), and it scales from smaller workshops right up to high-load warehouses and distribution centres.
At the heart of the range is a modulating ultra-low NOx burner setup, built to meet modern ErP expectations while giving you practical installation flexibility (free-blowing or ducted, upright or horizontal, internal or external).

CX “varieties” explained (what all the letters actually mean):
The CX range is offered in five main installation variants:
CX UF – Upright Free-blowing:
A vertical cabinet arrangement supplying heat directly into the space. Great for open areas where you want straightforward warm air delivery and good throw.
CX UD – Upright Ducted:
Same upright footprint, but designed to connect to ductwork for distributed air supply. This suits multi-zone areas, long buildings, or where air has to be delivered to specific points.
CX HF – Horizontal Free-blowing:
A horizontal arrangement where building layout or mounting constraints make a vertical cabinet awkward. Useful when air direction and physical clearance matter.
CX HD – Horizontal Ducted:
Horizontal format with ducted supply, typically chosen where plant layout dictates the orientation but you still need ducted distribution.
CX EA – External (Weatherproof):
The heater sits outside and supplies warm air into the building via ducting. This is ideal when indoor plant space is limited, air quality is challenging, or you want to keep combustion equipment out of the occupied area.
If you’re specifying ducted models, the ability to select different external static pressures is a big deal: it’s what lets the same heater platform behave nicely across different duct systems instead of fighting them.
Where the CX range is typically used:
Because CX is scalable and configurable, it shows up in the places where heating load, air movement, and uptime all matter:
- Warehouses and logistics: High ceilings, big air volumes, large doors opening and closing all day
- Manufacturing and production: Consistent temperatures for people, process, and equipment reliability
- Distribution centres: Fast recovery heating and controllable air direction to reduce cold spots
- Workshops and depots: Robust heating with practical service access
- Garages and heavy industrial spaces: Especially where an external (EA) setup keeps plant out of the work zone
- Large retail and trade counters: High footfall, frequent air exchange, need for stable comfort
- Sports halls and large activity spaces: Big volumes where warm air throw and control matter
In short: anywhere that needs “industrial-grade comfort” rather than a polite little trickle of heat.
Performance and compliance (why the CX spec reads like it means business):
A few of the CX performance points that are genuinely useful when specifying:
Ultra-low NOx focus: The range is designed around reduced NOx emissions to support ErP 2021 expectations for cabinet heaters.
Seasonal space heating efficiency: Around the high-70s to ~80% across the range (model dependent).
Modulating burner behaviour: Modulation helps the heater track demand more smoothly (less temperature swing, less stop/start stress, steadier comfort).
Air distribution control: Adjustable nozzle heads help aim heat where it’s needed, rather than just heating the roof space first.
Service access: Simple access matters more than brochures admit—downtime costs money, not just annoyance.
If you’re ducting, the headline isn’t only kW. It’s kW plus control of airflow, throw, and resistance (static pressure), because that’s what decides whether the heat actually lands where people are working.
Selection tips (how to pick the right CX without overthinking it):
1) Start with the building reality, not the brochure
Ceiling height, door frequency, insulation, and how “open” the space is will often push you up a model size faster than expected.
2) Decide: free-blowing or ducted
Free-blowing suits open areas where you can point the heat and let it mix naturally.
Ducted suits long buildings, multi-bay layouts, or anywhere you need heat delivered to defined zones.
3) Decide: upright, horizontal, or external
This is mostly about plant layout, clearances, and whether you want equipment indoors or out.
4) Check utilities early
Smaller sizes are typically 230V single-phase for standard fan supply; larger sizes move into 400V three-phase territory. Confirm this early to avoid awkward surprises.
5) Don’t ignore flue and combustion air details
Flue diameter and combustion air spigot sizes scale up across the range, so coordination with the building fabric and routing matters.
FAQ:
What sizes are available in the Powrmatic CX range?
Ten sizes covering 30 to 300kW, with maximum outputs from 29.9kW up to 300.6kW.
What does “EA” mean on the CX range?
External Application (weatherproof external version). The heater is installed outside and ducted into the area being heated.
Is the CX range suitable for ducted distribution?
Yes—choose UD (upright ducted) or HD (horizontal ducted). Ducted options can be specified to suit different external static pressures.
Why choose a cabinet heater over multiple smaller units?
Fewer appliances can mean simpler maintenance and controls, and a cleaner overall plant approach, especially in high-load industrial spaces.
Can the CX range support lower-emission heating goals?
It’s designed with reduced NOx performance and ErP compliance in mind, making it a more future-proof option for many industrial sites using Natural Gas (G20).
