High Temperature Ovens
A high temperature oven is a different machine from a drying box. Between 300°C and 500°C, stainless steel elements scale, insulation becomes the product, and a controller that drifts two percent can anneal your parts wrong. This is heat treatment territory: annealing, stress relief, powder curing, binder burn-out — processes where the result is measured after the parts cool. The WSHLab RGW series is a high temperature forced air oven built for exactly that duty. It reaches 500°C with Incoloy heating elements that survive where nichrome fails, a 316L stainless work zone with removable shelves, multi-layer insulation that keeps the exterior cool, and a PID controller with over-temperature protection on an independent circuit. Capacities run 42L, 72L, 150L and 400L. If your process tops out at 250°C or 300°C, a standard forced air oven is the economical answer — see the selection guide below. When the spec sheet says 400°C or 500°C, this is the series you quote.

Applications
Where 500°C earns its keep
Heat treatment, curing and preheating processes that a 300°C oven simply cannot reach.
Coatings and composites — powder curing and thermal-spray overlays
316L work zone resists process fumes
Electronics reliability labs — accelerated aging and burn-in at temperature
Independent over-temp circuit protects the load
Ceramics and materials R&D — binder burn-out and pre-sintering
400L model takes full trays
PERFORMANCE & SELECTION
What is a high temperature oven?
By convention, a high temperature laboratory oven works above the 300°C ceiling of a standard drying oven, running 400°C or a 500°C oven class. The engineering changes throughout: Incoloy-sheathed elements instead of bare wire, a 316L work zone instead of coated steel, and insulation thick enough that the outside stays touch-safe at full temperature.
- RGW range: RT+5°C to 500°C, resolution 0.1°C
- Forced convection with a high-speed centrifugal blower
- 316L stainless work zone, removable shelves, 15 kg shelf load
- High-temp silicone seal and latch door handle
CONFIGURATION & COMPATIBILITY
The 500°C model line: RGW 42L to 400L
Four sizes cover the bench to the bay: RGW-42D for laboratory work, 72D and 150D for shared R&D duty, and the 400L RGW-400D for sintering trays and full-size fixtures. Heaters scale from 2000W to 7500W, and every model keeps the same control layout.
- RGW-42D, 72D, 150D, 400D — 2000W / 3000W / 4000W / 7500W heaters
- Interior from 350×350×400 mm to 650×700×850 mm
- Two removable shelves standard, 15 kg per shelf

QUESTIONS & ANSWERS
High Temperature Ovens: frequently asked questions
The questions buyers ask most often when specifying High Temperature Ovens, answered by our technical team.
What is the maximum temperature of the RGW series?
500°C, with a working range of RT+5°C to 500°C and 0.1°C resolution. The controller is PID with an independent over-temperature protection circuit.
Are Incoloy heating elements standard?
Yes — Incoloy-sheathed elements are standard on the RGW series, chosen specifically for continuous 400°C+ operation where ordinary elements oxidise and fail.
What temperature uniformity can I expect at 500°C?
Forced convection keeps the work zone within ±3°C at 500°C, verified on the blower-driven loop with the PT100 sensor placed in the working volume.
What sizes are available?
RGW-42D (42L), RGW-72D (72L), RGW-150D (150L) and RGW-400D (400L), with interior heights from 400 mm to 850 mm and two removable shelves rated at 15 kg each.
Does the exterior stay cool?
Multi-layer insulated double-wall construction keeps the shell safe to touch at full setpoint — the same door handle you use at 200°C you still use at 500°C.
