Aisin Seiki gas heat pump air conditioning systems run on a clean energy source and use the new 100% non-ozone destructive refregerant, R407C.
As a decentralized energy source, gas helps reduce peak power demand in summer.

Aisin Seiki's gas engine cogeneration system produces electricity and sanitary hot water simultaneously by using a gas engine and generator. This system is connectable directly to the main electricity supply line through an inverter, thus achieving a high operating load factor.

Cryopumps offer ultra clean vacuum by using an ultra-low temperature (-250°C). Maintaining a freezer is easier by using the original valve mechanism.

Pulse tube cryo coolers generate low temperatures by vibrating helium gas. Elimination of pistons in expansion units enables low-vibration, maintenance-free designs.

Peltier modules enable to achieve cooling and heating in a microscopic space and precise temperature control by sending electricity to thermoelectric semiconductors.
