ATEX Certificated Variators

ATEX Certificated Variators

Atex-certified variators
For potentially explosive environments.

The Var-Spe variator is the ideal solution for potentially explosive and explosion-proof environments in compliance with the Atex 95 directive (94/9/EC): simple, sturdy and reliable.
Thanks to hydrostatic technology, they need no complicated and expensive monitoring devices.
All Var-Spe products can be supplied in accordance with the ATEX directive.

For Atex Zone 1/21 or zone 2/22 environments, both gas and dust, according to the following classifications:

Ex II 2 GDbc IP65 T135°C X
Ex II 2 GDc IP65 T180°C
Ex II 3 GDc IP65 T135°C
Cost-effective installation
Simple to use
Extremely competitive prices
High breakaway torques starting from zero rpm
Wide speed range, 0-1400 rpm for both directions of rotation
Standard adjustable torque limiter

Technology

Hydrostatic technology with radial pistons so there is no friction on the inside, making it reliable over time.

Characteristics

Power range: 0.37 up to 22 kW
Long service life
Zero rpm output with the motor running
Adjustment handwheel even with the motor off
