InvenSor GmbH presents adsorption cooling technology that uses waste heat to provide highly efficient cooling. Their adsorption chillers can achieve up to 90% electricity savings compared to compression chillers and use water as a refrigerant. Their chillers are available in sizes from 10-300 kW and are suitable for applications in plastic processing industries and other industries with high cooling demands. Tri-generation systems that combine heat and power cogeneration with adsorption chilling are a feasible option when electricity prices are high.

• High electrical power consumption
• High cooling demand
• High energy & maintenance cost to
provide cooling
• Long running hours
Ideal conditions for InvenSor
adsorption chillers!
• Low electrical power consumption
• Low maintenance cost
• Short return of invest times
Why InvenSor for the
plastic processing industries?

ADsorption & ABsorption – Difference?
Adsorption Technology (liquid/solid)
• Temperatures from 60°C can be used
Lower return flow temp. ideal for CHP
• Robust technology: no turning off, no
crystallization, no corrosion
• Dry recooling, low maintenance
• Simple system design and installation
• Compact unit incl. pumps, controlling, etc.
Absorption Technology (liquid/liquid)
• Typically above 80ºC needed
High capacity losses at lower driving
temperatures
• Crystallization risk: potential turn-off
• Wet recooling: water treatment, hygiene
(legionella)
• High maintenance needs of chiller (ie.
corrosion)
High design and
maintenance efforts
justified only for
large capacity range
Plug & play
systems with a stable
performance

Tri-generation
When is Tri-generation a feasible option?
• Price for electricity (€/kWh) ≥ 3 x price for natural gas (€/kWh)
Additional benefits:
• Replacing electrically driven chillers (refrigerants)
• On-site generation of electricity
• Reducing electrical peak loads
• Free Cooling option
• Future-proof refrigerant (R 718), ODP=0, GWP=0
• Reduced carbon footprint
• National / local subsidies (i.e. 25% on invest in Germany, Bafa)

Air Compressors as Heat Source
Air compressors are major
electrical power consumers
• 94% of the energy may be
recovered as heat
• This heat may be used to drive
