Building on more than 45 years of application experience with our unique ExVelTM turbo fans, Howden is pleased to offer the innovative, eMVR turbo fan. The simplicity of design, fit, form, function, and many options make the eMVR the EASY MVR solution for your vapor compression applications less than 10 tons of vapor.
The robust fan casing with an integral motor allows the user to install the eMVR directly to their vapor body, eliminating the need for costly and space consuming ducting and support structures. The unique ExVel impeller is the workhorse of the machine and is mounted directly to the motor shaft. A multi-stage carbon ring seal with purge and condensate drain provisions will ensure process steam remains isolated from atmosphere. The rotor bearing seals are separate and independent from the fan casing seal with ventilation between the two to ensure oil-free operation for the process steam, and isolation of process from the machine bearings.
A number of optional features such as but not limited to machine condition monitoring packages, seal purge conditioning packages, installation base, and more can offer the designer and user design flexibility, added functionality, and maintenance friendly operation.
