DelValle

We manufacture Polycarbonates custom made to the requirements of our customers.

Polycarbonate is excellent for electrical applications, because of its high dielectric strength and high volume resistivity which decreases only slightly as temperature or humidity is increased.

Polycarbonate is a tough, dimensionally stable, transparent thermoplastic that has many applications which demand high performance properties. This versatile thermoplastic maintains its properties over a wide range of temperatures, from -40″F to 280″F.

It is the highest impact of any Thermoplastic, transparent up to 2″ in special grades, outstanding dimensional and thermal stability, exceptional machinability, stain resistant and non-toxic with low water absorption.

Top Panels Fans The new delvalle Series has a low profile housing, only 90mm deep, and is designed for top mounting on the outside of cabinets, thus providing high level extraction of hot air whilst taking-up none of the valuable space within the enclosure.

The special attraction of this Top Panels Fans is its backward-curved impeller blade which sustains the flow of essential cooling air through the cabinet, even when the equipment packing density is high and the inlet filter is becoming dirty.

Door or panel-mounted inlet filters can be supplied from Axair’s renowned ‘FPF’ series, an invaluable product for keeping sensitive electronic equipment clean and therefore efficiently cooled.

The Top Panels Fans Series is available in two sizes providing air flow rates from 500 to 1000m³/h. Models are offered in a choice of 115 or 230V motor, in RAL7032 or 7035 colour, and with IP43 sealing gasket as standard supply.

Contactdelvalle Fans to discover how to draw more cooling air through your control panels and enclosures, keeping valuable electrical equipment operating for longer.

The delvalle Light for enclosures was designed to fit in tight spaces in enclosures. It features an integrated receptacle, so that electrical devices (e.g. power tools) can be easily plugged in when needed.

The standard light can be screw-mounted in a variety of positions, or the light can be fitted with an optional magnet mount. The motion sensor was designed so it can be used in enclosures with glass doors and not be activated by movement outside the enclosure.

Outdoor 19 ” Rack for Data and ICT

We have designed a smart range of 19 ” rack enclosures, especially for telecommunications and data applications. We supply a completely finished and mounted enclosure to save assembly costs, all the doors can be dismounted and the main door has a rotating handle. Our wide range of manufacturing possibilities offers customised design as standard, available from 21 U to 48U or even more. The enclosure design is fully ventilated in the upper part and can even house fans inside to force ventilation within the enclosure towards the outside, conserving the electronic components inside the enclosure in perfect condition.

Given the multitude of solutions we can offer for this type of enclosure, we can easily adapt to our customers’ requirements and make any proposed solution viable.

delvalle traffic enclosures  syste m solutions for optimising the flow of traffic by road, rail
and in the air.

The monobloc design of the outdoor cabinet allows IP 65 seal tightness and IK10 maximum possible resistance. A self-ventilating overhead cover and optional base can be included. With high resistance in the embedded doors, it is designed to be fully vandalproof.
Greatly increased levels of freight and passenger rail traffic are creating
completely new challenges for transport technology and monitoring.
State-of-the-art telematics systems are helping to organise the increasing
traffic flow efficiently. Networked systems require extensive protection for
the technology installed. The many external influences such as polluted
air, damage from stones and rocks, vandalism, rainstorms, and heat have
a decisive effect on the service life of the unit.

Delvalle offers the ideal enclosure for your intelligent, networked solutions for
every location:
●For radio applications in rail or airport areas
●For signal units along the road or railway track
●For free-flow or single-lane toll collection
●For monitoring and access control systems in external applications
●For all types and sizes of monitoring station
