Choosing The Right Enclosure For The Right Environment

Choosing The Right Enclosure
Craig & Derricott
When choosing an enclosure, care must be taken to select the most suitable material by considering:
- location
- level of pollution
- temperature
- UV levels
- vibration
- humidity
Typical enclosure materials include Aluminium, powder coated Mild Steel or Stainless Steel.
Enclosures that are sealed to IP65 are commonly mistaken as being suitable for all outside environments. Some powder coated mild steel or Aluminium enclosure may degrade and corrode under certain environmental conditions.
Installing enclosures in an external environment may also result in condensation forming on the inside of the enclosure, resembling water ingress. This is caused by a difference in temperature between inner and outer surfaces of the enclosure and the most common solution is to fit an anti-condensation heater and breather gland within the enclosure.
When the product is subject to chemical cleaning a stainless steel enclosure is recommended although the correct grade of stainless steel must be selected.
Please consult our expert technical department for help with choosing the correct enclosure for your application – this includes both safe “non-hazardous” types and ATEX enclosures certified for hazardous areas.
CRAIG & DERRICOTTÂ ISOLATORS
IECEx & ATEX Certified Isolators for Explosive Atmospheres
Isolators and control stations manufactured by Craig & Derricott are certified by ATEX & IECEx for Zone 1 (21) and Zone 2 (22) hazardous areas – the range of i-switch isolators are suitable for Ex d (flameproof) and Ex e (increased safety) applications and the i-push control stations are certified for Zone 22 potentially explosive dust atmospheres.
Craig & Derricott has been at the cutting edge of Explosion Proof Switchgear design and manufacture for more than 70 years focussing solely on the design specifications of the installer. This led to the development of the i-switch and i-push product range suitable for hazardous areas offering simple installation, enhanced safety and effectiveness for LV electrical isolation.
