Hydraulic versions

   KZV – Standard version (S)

Equipment with no hydraulic unit.

The KZV units feature triple protection for the plate heat exchanger. The series production version includes a flow switch, antifreeze protection for water and antifreeze protection for freon.


   KZV – Version with hydraulic unit (P)

Hydraulic unit composed of a circulating pump suitable for water or glycol water to 0°C, expansion vessel, bleed and stop valves, pressure gauges and a flow switch.

For temperatures lower than 0°C, the low temperature kit is required, which requires a replacement of the pump and adds electrical resistors to the hydraulic elements for work with water at temperatures as low as -10°C.

The hydraulic unit is built into the chassis of the standard version for all units up to the 2090 model. For higher models, the hydraulic unit is provided in an independent module.



Keyter series production MEDEA equipment includes the AQUAMANAGER programmable electronic control,

 specifically developed for the management of air-to-water and water-to-water equipment with the pGD1 user and maintenance terminal.
