⚠️ LIMITED STOCK AVAILABLE ⚠️

We currently have just 20 Honeywell UVZ780 Flame Detectors available.

As many engineers will know, these units are now obsolete and becoming increasingly difficult to source. Once these are gone, finding genuine replacements may become a real challenge.

If you're responsible for maintaining older combustion systems, now may be the time to secure a spare before availability disappears completely.

✅ Genuine Honeywell stock
✅ Available now
✅ Fast UK dispatch
✅ Technical support available

When they're gone, they're gone.

FAN RUNNINGBUT NO IGNITION?

One of the most common combustion faults and often one of the most frustrating to diagnose.

In many cases, the issue can come down to airflow proving and the pressure switch not confirming the correct conditions for startup.

Before replacing major components, it’s worth checking:

✔ Air pressure switch operation
✔ Pressure tubing for blockages or condensation
✔ Wiring and connections
✔ Fan performance and airflow
✔ Correct switch range/settings

Getting to the root cause quicker can help reduce downtime, avoid unnecessary replacements and get systems back up and running faster.

Need help identifying the right replacement pressure switch?
Our team can help.

In some applications, keeping combustion gases completely separate from the process airflow isn’t just important...it’s critical.

That’s where indirect heat exchangers come in.

At Comtherm, we design and manufacture indirect heat exchanger systems in-house here in the UK, supplying solutions for everything from low-temperature AHU systems through to higher temperature industrial process applications.

From CAD design and fabrication through to final assembly, every system is built around the specific requirements of the application.

✔ Low and high temperature solutions
✔ Bespoke configurations available
✔ In-house UK design and manufacturing
✔ Air-to-air heat recovery options
✔ Designed for efficiency, reliability and long-term performance

Used across industries including automotive, food processing and milling.

Not every application runs at full demand all year round.

In this AHU installation, we supplied a dual-stage in-duct burner system designed to handle seasonal fluctuations more efficiently, reducing unnecessary cycling during lower demand periods while still delivering full output when required.

Key features included:
✔ Independent gas trains and control motors
✔ Siemens LMV52 combustion control
✔ Four-point flame monitoring
✔ Integrated gas metering and bypass line
✔ Real-time flame signal monitoring and communications integration

By improving turndown capability, systems can operate more efficiently at lower loads, helping reduce fuel waste, minimise wear from repeated cycling and improve long-term reliability.

Strong partnerships are built on more than products.

From technical training and knowledge sharing to ongoing collaboration with partners and manufacturers, we believe the best results come from working closely together and continuously learning from each other.

Moments like this are a good reminder that engineering expertise doesn’t stop at the workshop door.

Some systems aren’t off-the-shelf. They’re built on experience.

Our work in tile drying ovens is a good example of the kind of projects we’ve supported over the years. Working alongside major manufacturers to deliver combustion solutions that are reliable, efficient, and designed around real-world production demands.

This isn’t just about supplying components.

It’s about understanding the process, the pressures, and what’s at stake when systems don’t perform as they should.

From global brands to specialist manufacturers, we’ve built long-standing relationships by doing things properly:
✔️ Strong technical knowledge
✔️ Practical, application-led design
✔️ Proven, reliable components
✔️ Support that goes beyond the initial supply

It’s this combination that underpins everything we do today. From bespoke projects through to the parts we supply every day via our online shop.

If you’re working on a system that needs more than a standard solution, we’re here to help.
