New more efficient fans

ZETA TOP units use the most modern EC axial fans with a diffuser, which ensure higher air flow with continuous speed control at the same power input.

 

New exchangers

We used a new heat exchanger geometry for the new ZETA units. The new slats have a pitch of 4.23 mm, which ensures better air flow and eliminates the risk of dust clogging. The exchangers are made of copper and aluminum by default to withstand aggressive environments. They can be provided with a special surface treatment and the housing of the unit made of stainless steel.

 

At the customer’s request, ZETA hot water heaters can be supplied with an exchanger with a vinyl surface of the lamella. Thanks to the vinyl, the lamella has a smoother surface and better resists possible dirt. It is especially suitable for dusty operations. The efficiency of heat exchange is not reduced in any way, the lamella is aluminum inside, only a thin layer of vinyl is applied to its surface.

Lots of accessories

We have prepared a large number of blinds and anemostats for the ZETA units. They can be connected to mixing chamber assemblies that can provide ventilation in the summer.

 

Remote control

It allows you to continuously change the fan speed from 0% to 100%, thus influencing the noise and performance according to your needs. It can also be switched to full power or the fan can be turned off completely.

Solutions for aggressive environments

You can also order the aggressive environment version of a ZETA TOP unit. Here, the exchanger is fitted with a special, highly durable surface. The whole device is made of stainless steel and the electrical part has increased ingress protection rating of IP 54, including an all-plastic fan. These units are widely used in agricultural production in animal husbandry or meat processing.
