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
- Remote dashboard for you and for GreenSeed®
- 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
