We offer various design of drying and curing oven also with latest technology using Infra-Red (IR) system configurations with low energy consumption. This is achieve with the optimum air flow design, such as elevated oven design, floor oven with force air seal system, high density insulation and more. High quality heating element is used to ensure reliability and efficient heat transfer, high efficiency fuel/gas burners ensure complete combustion and maintain low fuel/gas consumption.
Type Of Oven
In former years, there was a tendency to oversimplify oven problems. There was a widely-held idea that an oven was “just a heated box” through which parts were passed in order to dry or bake a finish, to evaporate and remove moisture, or otherwise process by heat application.
In more recent years the scientific aspects of heat engineering have come to be appreciated, in many cases prompted by developments pioneered by Fextec.
True economy in operation, matched by superior results, can only be obtained by expert design based on sound engineering, followed by quality manufacturing and conscientious installation. Even on the smallest ovens, the Fextec approach saves on initial cost and all important operating costs, insures first class results and guards against excessive maintenance.
The ovens shown herein are merely sample of the many type built by Fextec, each representing dozens and even hundreds of similar installations. Many special types are not shown. We will be glad to consult with you, without cost true or obligation, on any heat application problem.
For standard ovens, custom designs, or economical prefab components, it pays to consult the true experts in heat engineering. You can “ Fextec Engineering Sdn Bhd with confidence.”
FLOOR MOUNTED
This large monorail conveyor oven installation incorporates two oven: a dry-off oven which dries parts after cleaning ( 150°C for 10 minutes ) and a combination prime and finish baking oven ( 200°C for 20 minutes ). The drying oven is 44’ long; the baking oven is 38’ by 62’, incorporating multiple passes within this space. Conveyor speed is 8’ per minute.
ROOF MOUNTED
Parts are loaded at floor level, then travel sharply upward to enter the oven. The dry-off oven operates at 150°C; prime baking is done 200°C for 15 minutes and finish baking at 200°C for 15 minutes. Conveyor speed is 4’ per minute.
TWO ZONE
Note the dual controls on this two zone oven. The recirculation fans are in the top of the combustion chamber. The burners are mounted in the bottom of the chamber. When burners are mounted low, dust and dirt create a problem. Therefore, filter are required on the burner inlet.
A-TYPE
The natural tendency of heat to rise, plus the availability of unused ceiling space, makes the elevated oven effective and space-saving as well. Since the oven is elevated, no valuable floor space is used, other than for loading and unloading stations. The bottom entry and exit openings, which are self-sealing and help to control plant temperatures and conserve energy.
BATCH
Truck or rack type oven offer economies in initial cost and during operation as well. Oven trucks, racks of parts or larger parts are placed in the oven through doors of convenient size and location. Time and temperature are easily controlled for any desired result in paint finishing.
Oven Feature
Knowledgeable plant operations personnel, on seeing their new Fextec Oven assembled, often tell us that Fextec construction equals or exceeds any they have ever seen. Fextec Oven panel and general construction provide maximum strength and rigidity, minimum heat transfer or loss, plus an extremely attractive appearance.
Air Seals – Fextec Ovens can be installed with a variety of seals to prevent escape of heated air and fumes. The A-type oven, which must elevate, has a natural type of seal because the heated air rises into the upper, sealed portion of the oven. Exhaust type seals, in which conveyor opening are enclosed by a hood with exhaust fan, are also available.
In theory, the most practical type of seal is the re-circulating seal, which has been far from perfect in the past. Fextec has invested considerable time and money in this seal and is now producing re-circulating seals which allow adjustment to compensate for various oven temperatures.
Rolling Air – An exclusive Fextec development, induces an air movement which helps to obtain remarkably even temperatures. The air movement is induced by Fextec high velocity nozzles. The nozzles also prevent direct impingement of heated air on the work surface, a notable cause of “skin-drying” and resultant bubbles and blemishes.
Burner Size – In selecting burners for an oven, Fextec engineers concentrate on the total needs of the job at hand, then allow for a reserve capacity which will handle higher work loads with out expensive alterations. This provides the greatest overall economy and equipment flexibility because the burners are efficient throughout their operating ranges.
Combustion Chambers – Fextec Oven are usually designed with the combustion chamber as an integral part of the unit, streamlining the appearance and eliminating the need for exterior dust work. This compact arrangement also reduces power requirements connected with excessive dust-work, saving floor space as well.
Disposable Filter – When desired, intake air filter will be provided, minimizing intake of dust which can cause finish flaws. The filters are arranged for quick and easy changing without use of tools. The disposable filters used are frameless, eliminating the usual cardboard frame as possible fire hazard.
Simple Erection – Fextec oven are constructed of pre-fabricated panel for easy erection. All parts, panels, structural, duct work, wiring and piping are keyed to assembly drawings and manufactured to fit easily, quickly and precisely in the field. He purchaser can, in many cases, erect the oven with his plant personnel under Fextec supervision, for significant savings. On more complex ovens, Fextec provides a complete service, ranging from basic erection to complete commissioning.
A finishing system may have many possible arrangements, but only one is the best suited to user plant condition and needs. Only
Selection of the material handling method varies directly with the production volume, part size/ shape/ weight and desired cleanliness. In general, the
