RESTART PRODUCTION FASTER AFTER EVERY WASHDOWN

Washdown cycles are a necessary part of the food processing business — but you’re not making money while that equipment is down. And the longer those washdowns take, the more time bacteria has to fester and grow. Adequate heating and ventilation are critical to keeping washdown cycles as short as possible.

NOWHERE TO GO? TRY UP

The roof may not seem like an easy place to mount ventilation and drying equipment, especially if yours is a spiderweb of steam pipes, gas lines and ductwork. Unfortunately, most airflow systems are so big and heavy that you have to punch holes in walls or add structural supports. But that’s not a problem for compact vertical units that quickly drive hot air precisely where it’s needed. 
This type of system is a lot more efficient than traditional centrifugal designs. Not only do they require a fraction of the energy cost, they can cut several hours off every washdown cycle. 
A roof-mounted vertical solution doesn’t require you to reroute, add or work around ductwork, cut extra holes in your building, or take up valuable space with extra supports for the system. In many cases, they can be mounted over existing roof openings with prefabricated curves.
You’ll also gain the flexibility to mount the system directly over problematic areas for concentrated drying and ventilation. Areas that require more frequent washdowns can be serviced without shutting down the rest of your facility.

SAFER MAINTENANCE

While keeping work areas sanitized in less time is the primary benefit of vertical units, you can improve employee safety by eliminating condensation and slick floors. Because of the space-saving nature of vertical solutions, these units are generally direct-drive with external plumbing tranes. With no belts to change, no fan bearings to lubricate, and easy plumbing access, you’ll stay OSHA-compliant with less costly and time-consuming maintenance.

SOUNDS GREAT, BUT DOES SUCH A SYSTEM REALLY EXIST?

Yes, space- and cost-saving vertical units exist, but there’s only one on the market: the Series 78V from Hartzell. With a footprint that’s just 64¼ in2, the 78V can deliver up to 2,900,000 BTU of tempered air with no duct runs. You’ll also use one-third the energy (5 HP, versus the 15 HP used by centrifugal designs).
