GREENSEED®RecoveryPLUS
GREENSEED® Pioneering Intelligent Water Heating Solutions Since 2012
GreenSeed® RECOVER+ is a waste heat recovery unit that captures the heat now lost up the exhaust of gas-fired flatwork ironers, boilers and steam generators, and uses it to pre-heat water. Hot exhaust passes through a 316L stainless steel finned-tube counterflow heat exchanger. The cold water picks up that heat and goes on to TANK+ or the boiler feed, so they burn less fuel. A reference unit is rated at about 60 kW. theBRAIN controller measures every kWh it recovers. GreenSeed® funds, installs and maintains the unit at zero upfront cost, and is paid only on the heat actually measured. RECOVER+ is currently a pilot product, and pilot sites are open.
How RECOVER+ works
Exhaust in: hot exhaust from an ironer vent or a boiler flue enters the unit.
Heat reclaim: the exhaust flows through a finned-tube counterflow exchanger against cold water. The coldest water meets the already-cooled air, so heat is still recovered at the very end.
Pre-heated water out: the warmed water goes on to TANK+ or the boiler feed. Moisture in the exhaust condenses at the cold end and drains away.
One core, two heat sources
Ironer exhaust: humid air at around 100–110 °C, rich in latent heat, with condensate close to neutral.
Boiler and steam-generator flue: dry, hot gas at around 200–260 °C, mostly sensible heat, with acidic condensate. That’s why the whole core is 316L stainless steel.
Both streams can be recovered in series on one site.
Built to cope
316L stainless steel tubes, fins and flanges
Lint filter for the ironer vent
Condensate drain at the base
Handles acidic boiler-flue condensate
Design temperature up to 260 °C
Mounted on top of the flatwork ironer on adjustable green steel legs
Range
FG-50: one core, about 50 kW class. For an ironer vent or a boiler flue.
FG-100: two cores in parallel on a balanced manifold, for larger boiler exhaust.
The range scales by core count, and the final rating is confirmed per site.
theBRAIN: every kWh counted
Reads four temperatures and the water flow
Works out live kW: flow × 4.186 × (T out − T in)
Totals cumulative kWh, RM saved, CO₂ and payback

Tamper-evident, so the numbers can be trusted
The deal: zero upfront cost
GreenSeed® funds, installs and maintains RECOVER+. In return, we share in the value of the heat it reclaims. That share isn’t tied to years or a fixed price. It’s tied to the cumulative kWh actually reclaimed, and it falls as the total grows. If you want out, you buy out the balance not yet reclaimed.
H2: Who it is for
Plants with a gas-fired flatwork ironer, or a boiler or steam generator, and hot water use close by, such as commercial laundries, hotels, hospitals and factories. RECOVER+ pairs with GreenSeed® TANK+ and BRAVO
