Tyre & rubber industry · Jetomat TurboHeat®
We close the steam loop on your curing presses. One variable-nozzle Jetomat per bank of presses keeps steam moving through every mould, takes the blow-through back and sends the condensate home hot and closed.
Jetomat® variable-nozzle thermocompressors, made in Germany by Baelz. Engineered and commissioned in India by i-Kcal.
Where it leaks
Curing presses take about four-fifths of a tyre plant’s steam, and three-fifths of the cure heat goes into the moulds. Six things we hear first when we walk a curing hall.
Mould and bladder condensate flash the moment they reach an open tank: steam already paid for, leaving through the roof.
A trap on every mould circuit and a timed drain or bleed on many bladders: live steam passes all three, all shift.
The first fix on the floor is the trap bypass, opened a turn and left there: live steam straight to the tank.
Four to six tonnes of steel per press come up to temperature after every mould change and weekend.
Water in the curing header adds to the bladder pool; turbine exhaust brings superheat into it.
Fear of a worn bladder keeps all press condensate out of the boiler, though mould condensate is clean.
What changes
15 to 25% of the steam heat to the moulds comes back: about 7 to 12% of the plant’s steam.
In saturated steam, pressure is mould temperature: the bank holds ±0.05 bar at 7 bar g, a quarter of a kelvin at every mould.
Jetomat thermocompressorEvery mould drains untrapped into one falling return, and the Jetomat takes the blow-through back instead of passing it to a trap.
How the Jetomat worksA separator per bank, and one 3 bar g flash vessel per 25 to 50 presses on the bladder side, send the condensate back to the boiler house closed.
Condensate & flash recoveryThe Jetomat fails closed and a bypass opens at the same setpoint: curing continues.
Talk to an engineerThe bladder drain and exhaust go to closed recovery; the start-of-cure air purge stays vented, and a conductivity and turbidity guard diverts only a bad batch.
Condensate & flash recoveryA compensated steam meter on the bank and a totaliser on its return show the kg of steam behind every cure.

Proof
Tyre curing presses · South Korea
On a tyre press row in South Korea, one controlled Jetomat sits on the mould-heating header and every mould drains untrapped into one closed vessel that feeds it. Each press has its own Jetomat on the bladder side, and the purge steam is recovered.
How it works
The short version. The engineering detail is on the Jetomat page.
High-pressure steam from the bladder header enters the Jetomat’s variable nozzle and does the pumping.
The bank supply feeds every press in parallel; each press returns through its own isolation, balancing and non-return valves into one falling return and the bank separator.
The separator’s vapour is the Jetomat’s suction, so the blow-through returns to the moulds; only the condensate goes back to the boiler house, hot and closed.

FAQ
15 to 25% of the steam heat to the moulds, about 7 to 12% of plant steam. Your own meters set the number.
Only the mould-side steam path changes; the bladder sequence stays the press’s own. Every press gets a return-temperature alarm, and a cure-start permissive can tie the bank into your press PLC.
It fails closed, the bypass opens at the same setpoint and curing continues. A press fault is isolated by that press’s own valves.
Yes. A tyre press row in South Korea runs the same bank, and Michelin’s tyre presses reuse 15 tonnes of press exhaust steam a day through Jetomat jet pumps. i-Kcal’s Jetomats run on presses, a corrugator and dryers in Indian plants.
Domes stay off the bank: a Jetomat per press or closed dome-flash recovery. Different recipes get a bank per setpoint, or a Jetomat per press.
Where the bladder runs on nitrogen or hot water, the mould-side bank works the same.
Space the cure starts in the press controls first; then a steam accumulator charged from spare steam stores what spacing leaves. i-Kcal designs and supplies the accumulator.
Yes: belts, hose, moulded goods and drums, wherever steam is blown through a platen, drum or chamber. Conveyor-belt vulcanising presses take a Jetomat per platen, or one Jetomat on two platens in parallel.
Typical payback for a Jetomat is 6 to 18 months, depending on the application and the fuel price. Send the ten numbers and we work out what it means for your bank.
