Reliability against the elements. ZeroDT "Zero Down Time" against overvoltage surge events.

There is more to look at than the cost of your equipment to be replaced. There is planning, engineering and the labor cost to commission your process. Holliday Process Solutions specializes in specifying overvoltage surge protection for any process or application.

Holliday Process Solutions is proud to be a master distributor for the ZeroDT product line and we specify or recommend they be put in almost every solution we provide.

The ZeroDT Technology


The ZeroDT "Zero Down Time" utilizes non-degrading Silicon Avalanche Suppression Diode (SASD) technology to combat induced over voltages. Whether these events are weather related (lightning) or delivered from brown outs, black outs or grid switching, voltage is voltage. These very brief "spikes" in voltage can cause severe and catastrophic damage to our electronics, which in many cases tend to be the infrastructure of several different processes. This technology possesses several attractive characteristics most surge protection lacks. Silicon Avalanche Suppression Diodes or (SASD) do not degrade with use. They act simply as a voltage controlled switch, turning on/off thousands, even millions of times without losing their original performance. The ZeroDT has found a niche in several different industries protecting delicate instrumentation. Why? ZeroDT is small enough to mount inside of the equipment you want to protect. Real estate is key. The rule of thumb when it comes to surge protection is to mount your surge protection device or SPD as close to the protected equipment as possible. As wire length is time and time is of the essence, these transient voltage spikes are very fast and wreak havoc on electronics. The ZeroDT provides passive transient surge protection for both 24VDC and communication loops (2 loops per unit). Applications include both discrete and process automation instrumentation. ZeroDT is a 24VDC Surge Suppressor. Patent Pending. Made in the USA.
