Six ways we get heat-treatment furnaces holding temperature, uniformity and cost again, engineered to your process.
Services
Parts coming out uneven, cycles getting longer, energy creeping up: we measure atmosphere influence, heat loss, temperature uniformity and the control philosophy, then tell you what's causing it and what we'd change.
Most furnaces are worth saving. We rebuild them in place: refractory and insulation relining, instrumentation, atmosphere panels, cooling systems, conveyor changes, controls and full overhauls, engineered as one system rather than a list of patches.
A Temperature Uniformity Survey shows how evenly the furnace heats across the load, referenced to standards such as AMS 2750. You get documented results you can put in front of an auditor, and a clear picture of where the furnace drifts.
We convert gas- and oil-fired furnaces to electric resistance heating: sized from a heat balance, with elements, insulation and thyristor control engineered for your temperature and atmosphere.
Scheduled inspections catch element, refractory, atmosphere and control wear before it stops production. When something does fail, we diagnose it on site and get the furnace running again.
We specify and supply the parts a solution needs: heating elements, radiant tubes, fan impellers, thyristor controllers, seals, muffles, retorts, refractory and instruments, chosen for your temperature and atmosphere rather than off a shelf.
Health assessment
Most furnace problems show up in one place and start in another. These are where we look.
A furnace that runs long cycles, rejects parts or eats energy rarely has one cause. Measuring all four together separates the symptom from the fault, so the fix is the right one the first time.
You get what we found and what we'd change, in plain terms, before you commit to any work.
Proof
RetrofitPit furnace
An automotive components manufacturer's pit furnace re-lined with a Fibrothal heating system and ROB elements designed for line voltage, so the power transformer and its losses could go.
RetrofitSealed quench furnace
A bearing manufacturer's sealed quench furnace was not in working condition. We rebuilt it across eight workstreams and handed it back to production in January 2026.
ElectrificationSealed quench furnace
A gear manufacturer's gas-fired sealed quench furnace converted to electric heating, with elements in radiant tubes and thyristor control, running at 920–980 °C.
New furnaceBell furnace
A new 60 kW bell-type annealing furnace for cast iron: a Fibrothal heating system, two heating zones and a PLC control panel with SCADA, running at 950 °C.
RevampRotary hearth furnace
A bearing manufacturer's rotary hearth furnace kept losing element connections and hood insulation. We redesigned the elements and their cold zone, and relined the hood with high-temperature ceramic board.
RetrofitAluminium holding furnace
An aluminium holding furnace where every crucible failure took the SS310 heating elements down with it, for 15 days at a time. We rebuilt it with a Fibrothal heating system and Kanthal AF elements at line voltage, and a crucible problem now costs about 2 days.
