Oklima SM is a series of hot air heaters that offer a large flow rate and use direct combustion technology.
These heaters are equipped with an axial fan that allows for uniform distribution of hot air , ensuring high performance and a thermal efficiency of 92÷93% .

The SM series is available in different variants, selectable from the drop-down menu :
To ensure maximum protection and durability of the heater, a burner cover drawer has been implemented, which protects against impacts, dust, water and atmospheric agents.
Furthermore, the burner is equipped with a snorkel socket , connected to an intake sheath from the outside , to ensure clean combustion air.
The SM series has been improved with a new heat exchanger and higher performance fans , allowing for high thermal efficiency .
The machine's supporting structure is firmly anchored thanks to sturdy fixing brackets , allowing easy movement on any surface .
Furthermore, the removable panels make internal washing, even with the machine hanging, a simple operation .
To ensure greater strength and rigidity , the panels have been designed with cross-shaped reinforcement folds .

In the construction, only metric screws and inserts are used, avoiding the use of self-tapping screws, a choice that ensures greater safety and protection of elements subject to impacts and atmospheric agents.
The SM series fan is designed to ensure IP55 protection , in compliance with the European directives ERP 2009/125/CE target 2015 .
Furthermore, it is very quiet, with a noise level of less than 67 dB(A) at a distance of 2 metres, its 7 blades ensure a high air flow and static pressure , allowing a uniform diffusion of hot air through the sheath.
The fan's nozzle channels air to ensure higher static pressure .
The heater is equipped with two electrical panels , both with IP65 protection .
The rear control panel is positioned at the rear of the machine to avoid contact with dust, water and snow .
It is also equipped with a sturdy metal cover that allows for the storage of tools and documents .


The front service electrical panel is located on the front of the heater, inside the burner cover drawer .
This position facilitates maintenance and allows for easier control and intervention by the operator.
To simplify installation and maintenance , each main component of the heater (fan, burner, thermostats, etc.) is equipped with quick connections for electrical connection .
This allows for quick installation and disassembly and prevents errors during technical operations.
