The NCV furnaces have been constructed to satisfy the request of treating charges horizontally in alternative to the traditional pit furnaces, combining the advantages of the pit furnaces (see the containing retort in steel) with the operativeness of the chamber furnaces.
The most important innovations of the last ten years have been applied and the strongest points are:
- temperature and consequently treatment uniformity;
- the possibility to use gas heating alternatively to the electric heating which provides considerable advantages for both production and quality;
- the easiness with which the vacuum can be applied in various points of the cycle according to needs;
- the simple and maintenance-friendly sealing system;
- the process control which includes the automatic gas adjustment by means of mass-meters, with constant control of the internal pressure;
- the prearrangement for the insertion of various probes or analysers that the market offers at present.
Moreover, a high efficiency can be attributed to the rapid charge-cooling system, which works by making warm gas circulate in an external heat exchanger.
The door can be opened both sideways and vertically, thus facilitating the integration in automatic loading/unloading systems.
In the following, we will see some interesting applications.

The advantages of heat treatment in an Ipsen vacuum furnace are obvious: the edge zones of the workpieces remain free of oxidation
and decarburisation, also complex geometry workpieces can be treated with minimal or no distortion. Ipsen vacuum technology stands out
in particular because it provides a high, constant quality level and with it ensures that desired, repeatable treatment results are always achieved.
In addition the following processes can also be carried out:
AvaC® (low pressure carburisation),
AvaC®-N (low pressure carbon nitriding),
bright hardening,
bright annealing,
solution annealing,
bright tempering,
degassing,
hard and high-temperature brazing,
sintering,
SolNit®.

IVA vacuum chamber furnaces series VH…U/K, equipped with gas cooling, a reversal system and hot gas circulation, are mainly used for heat treatment of tools made of tool steel and high speed steel at temperatures ranging up to 1,300°C.
Quenching under a nitrogen pressure of up to 10 bars, controlled cooling and heating bath simulation offer possibilities to apply a wide variety of quenching conditions.
The furnace unit is designed for easy maintenance, i.e. all internal elements such as the heat exchanger, circulation fan with impeller and the convection unit are easily accessible.
The transformer, pump station - rotary slide gate and roots pump as standard equipment - the switchbox and gas storage container are arranged according to the local situation to save space. The assembly work is limited to connecting these system components and attaching the system to the energy supply.
The freely-programmable control system and a microprocessor-equipped programming unit offer very flexible program design.

Evacuable chamber tempering furnaces, series RH…RVe/g, are mainly used to temper and anneal materials treated in vacuum hardening furnaces. The RH...RVe type furnaces are electrically-heated, whereas the abbreviation “g” is used for gas-heated models.
The systems consist of a furnace body with modern, low heat-retaining insulation and the horizontal sliding retort with a gas circulation unit.
The integrated indirect cooling system permits cooling under a protective atmosphere (inert gas). The pump stand consists of a mechanical vacuum pump with the associated measuring instruments.
The switchgear is equipped with a freely-programmable process control system. The selection of this equipment permits very flexible process design.
The IVANIT unit permits nitriding, nitrocarburizing and oxidizing in evacuable tempering furnaces.
Moreover, the furnaces can be equipped with a specially developed rapid cooling system on request. This system achieves direct cooling of the nitrogen atmosphere, radically reduces the cycle times and thus renders IVA chamber tempering furnaces even more economical.
In combination with IVA vacuum chamber ovens, series VH...U/K, these evacuable tempering furnaces offer an attractive package for hardening and tempering of tools made of hot-work, cold-work and high speed steel.
