FAQs

What does it mean that an Optyma unit is “multi-refrigerant”?

It is designed and certified to work with several refrigerants without changing components. You can switch from R-404A to R-448A, R-449A or other replacements simply by adjusting the charge and the controller parameters, making F-Gas compliance easier without buying a new unit.

What is the difference between the OP-LSV, OP-MST, OP-MSI and OP-MSS models?

The letters mean: LS = low temperature, MS = medium temperature; T = standard AC fan motor, I = EC inverter fan motor (high efficiency), S = standard, V = with electronic controller. MSI models are the most efficient, as they include variable speed on the condenser fan.

How much noise does an Optyma Slim Pack unit make?

The sound level varies between 48 and 62 dB(A) at 1 metre depending on model and capacity. Models with EC fan motors are significantly quieter at part load, making them suitable for installations in residential areas with local noise restrictions.
