& EXAMPLES OF APPLICATION

The model of an Air Conditioner series MAC is defined by a basic code, composed as follow:

M: Manufacturer’s code (EMB)
AC: Air Conditioner
(P)-: for Pressurized Cabinets*
CWM: Conditioner Wall Mounting*
CRM: Conditioner Roof Mounting*

*Acronyms used only in the Codes of Air Conditioners for Exp Pressurized Cabinets

CW: Cooler Wall mounting
CR: Cooler Roof mounting
X: Ex Air Conditioner

. . . :  Cooling Capacity in W, expressed by a 3-digits number consisting of the 2 first digits of the power value and of a third digit indicating the quantity of following “noughts” that complete the value itself

The indicated below 7 models, where the second digit is 1, belong to second generation Air Conditioners

For the complete definition of the model, it is necessary to integrate the basic code, with further acronyms, relating to the power supply voltage, the Refrigerant Gas type, as well as to any optional, accessories and/or special versions

The acronyms can be deduced from the respective brochures

The MAC series includes the following types of AIR CONDITIONERS
