Doyma: Preventing Structural Damage

Doyma are the sealing systems specialists for pipes, cables and ducts running through walls, ceilings and floors.
Pipes and cables are used to supply industrial plants, along with commercial and residential buildings. All too often the focus of attention is restricted to the function of the water, gas, electricity or data supply. Little attention is given to the sealing and housing of pipes and cables passing through walls and ceilings until it is too late and structural damage has already occurred.

Doyma offers top quality, tried and tested ducting systems which ensure lasting protection against gas and water penetration and insulation against noise and fire. Doyma therefore provides excellent preventative measures against structural damage.

Doyma: Curaflex® sleeves

 Curaflex® sleeves, whether manufactured from special fibre cement or from steel, are an important element of the proven Doyma system for pipe and cable penetrations through buildings. The sleeves are manufactured, in accordance with the numerous constructional requirements, from special fibrous cement and/or steel for the commonly encountered conditions of pressing and non-pressing water and ground moisture.

Doyma: Curaflex® gasket inserts

Curaflex® gasket inserts: Doyma develops and produces gasket inserts for sealing penetrations through walls, ceilings and floors for the widest variety of situations. The spectrum of applications for gasket inserts encompasses structural and civil engineering, especially water lines, heating and district heating. Other applications include, for example, service ducts in swimming pools, bund and tank installations, gas pipes and civil defence shelters. Further uses occur in manholes, sewage works and in constructions with or without tanking membranes and thick coating renders. The Curaflex® gasket inserts fulfil the following construction engineering requirements

  • Sealing against pressing and non-pressing water. 
  • Gasket inserts for sleeves as well as core bores. 
  • Split versions for retrofit installations. 
  • Angular deviations up to 8°
  • Fire protection: With intumescent systems tested and approved to DIN 4102 of the Building Regulations, fire compartments can be penetrated with confidence. 
  • Explosion protection.

Doyma: Curaline® cable penetration systems

The Curaline® cable penetration systems BKD and KD are quick and straightforward gas and pressing watertight ducts for cables and cable ducts. All cable diameters are simply and flexibly sealed. Rounded edges of system components ensure cable insulation is not damaged when cables are pulled through. Curaline® cable penetration systems comprise watertight sleeves and a variety of cable adaptors. Heat-shrink shrouds with heat sensitised adhesive provide the pressure seal between the adaptor spigot and the cable.

Doyma Curaline® leakproof sleeves

Doyma Curaline® leakproof sleeves are installed single or double ended, either individually or alongside each other as a battery. By the innovative combination of an expanding seal system and a flanged sleeve, the system ensures a secure bond in the concrete. Both the BKD and KD systems are delivered to site in the correct length to suit the structure thickness.
 

Doyma Curaline® cable adaptors

Doyma Curaline® cable adaptors offer versatile solutions for sealing cables and cable ducts. The BKD cable adaptor, with its bayonet lock system, offers even quicker and easier installation. The KD system cable adaptor has a screw-thread slip ring and offers the same properties as the BKD system. Cable adaptors allow cables of various diameters to be ducted. Heat shrink shrouds are supplied as standard; shrouds using cold shrink technology are optionally available.

HIDRIA-GIF - DEMOUNTABLE VENTILATED CEILINGS FOR COMMERCIAL KITCHENS

Hidria-GIF’s unique demountable ventilated ceilings, using our patented cassettes, guarantee an hygienic, temperate atmosphere in all types of commercial kitchen.

Knowledge and experience gained over more than 20 years, of the difficulties confronting designers and catering staff serve as a mentor to GIF’s growing team of specialist engineers and technicians who, daily, develop solutions to the problems individually posed by each installation.
 

Hidria-GIF: demountable ventilated ceiling

GIF ventilated ceilings operate as overall surface supply and extract fields. The individual cassettes separate fat and condensate by harnessing the physical phenomena of moment of inertia and condensation. The 3-phase separation chambers are so constructed that dirt, fat and other suspended particles settle on the inner faces of the small registers. By using standardised, removable cassettes, access to all services passing through the plenum is straightforward.

The Hidria-GIF Restaurant system provides concentrated extraction and compromises heavy duty cassettes, blank tiles and fat collection channel within a dropped frame. It is specifically designed for those particularly intensive kitchens with extremely high fat and steam vapours encountered in the preparation of haut cuisine menus.
Advantages include:

  • Concentrated extraction above vapour intensive equipment
  • Extended cleaning intervals
  • Simple installation and removal of cassettes
  • Optimum hygiene and durability of stainless steel
     

Hidria-GIF: UV-C(lean)

The UV-C(lean) system that eliminates organic fat and grease particles in the kitchen exhaust air by means of UV-C light.

Oils and fats are carbon-hydrogen compounds whose individual molecules are made up of several carbon atoms; these are simple or complicated compounds that are attached to each other.

  1. By exposing greasy surfaces to intensive UV-C rays, a part of the energy from the UV-C light is absorbed by the fat and grease particles. Through this the molecules in the fat are put in a state of energetic movement which, in turn, makes an oxidation of the molecules substantially easier.
  2. At the same time, due to the influence of the UV-C rays on the oxygen molecules in the air, Ozone, whose oxidation capabilities is much greater than that of normal oxygen molecules, is created. 

These two processes cause an immediate oxidation of the fat molecules (a so called cold combustion). The resulting products of the oxidation are short-wave gaseous organic compounds (e.g. carbon dioxide), which are then conveyed to atmosphere by the extract air stream.

The GIF UV-C(lean) system is fitted with a new generation of UV-C lamps, having a higher output and energy, thereby giving greater efficiency within the same space.
UV-C(lean) systems work without the usual loss of efficiency, when operating in areas of raised temperatures. This means that the systems installed in extract canopies and GIF –Restaurant systems above grills and fryers function more efficiently and durably.
