For outputs of 1000 to 8000 Kr/hr

Pyro’s range of medium-sized gas-fired ovens are used if the mode of heating is preferred to electrical. Delivering the same superior productivity and performance, applicable for a wide array of applications with a compact footprint, these gas-fired ovens are high in efficiency and in yield.

Stress Relieving

Pyro’s reputation for valve spring expertise started with General Motors in 1997. GM purchased a Pyro electric oven, which allowed them to reduce cycle time from 35 to 9 minutes, from coiler to the end of conveyor. Moreover, with a much shorter preheat time of 10 minutes compared to the 45 minutes for a conventional oven, GM increased available production time by almost 4 weeks per year, and achieved considerable energy savings.


Another Pyromaitre success story concerns tempering of hydro-formed torsion tubes. The conventional process was a 60-minute continuous batch process with an incredible 1056 parts per batch. The lean solution delivered on three different continents uses a 10-minute process with only 60 parts. This high-speed processing provides the opportunity for single-piece workflow thus eliminating part fixtures and external handling equipment. Additional benefits include a simplified and more robust robotics program and significantly reduced capital investment.
