Kostan 9 Tray Gas Convection Oven

The oven runs on natural gas with a 1/2" gas inlet and 20 mbar pressure, and can also be configured for LPG on request. A 220V single-phase power supply is sufficient for the fans and control panel. The oven’s electrical power is 1 kW and the proofing cabinet power is 2 kW.

Both models have the same capacity, tray size and proofing cabinet; the difference is the energy source. Kostan 9 G draws its heat from natural gas, uses only 1 kW of electrical power and runs on 220V single-phase. Kostan 9 E, on the other hand, runs entirely on electricity and requires a 380V three-phase connection and 18 kW of power.

We manufacture professional ovens for the bakery and patisserie industry: rotary convection ovens, deck ovens, artisan bread ovens, convection ovens, multi-function ovens and vertical proofing cabinets. Our range covers capacities from 2 to 20 trays and is available in both electric and gas versions. Share your daily production target and available space with us, and we will recommend the most suitable model.

220V and 380V, 50-60Hz are standard in our production. Gas models run on 220V, while electric ovens are produced in 220V or 380V depending on the model and capacity. Gas models can be configured for natural gas or LPG. When requesting a quotation, please specify your electrical supply and gas type so that your oven is built to these specifications from the start.

All İmproven ovens are manufactured at our own facility in Bursa, Türkiye, in accordance with international quality and safety standards, and carry CE certification. Every oven is tested before it leaves our factory.

Standard models are dispatched directly from stock when available. If not in stock, production takes 10 working days after order confirmation. For customised or high-capacity models, this can take up to 20 working days, and for bulk orders, 3 to 5 weeks depending on the model. Delivery time varies by destination; once you share your delivery address, we will inform you about the transit time as well.

Before delivery, we send you the technical drawing and installation requirements for your model so you can prepare your site. You will need a forklift at the delivery address to unload the oven from the truck. In addition, please make sure the following are ready: a level floor with sufficient load capacity, an electrical connection matching the oven’s power rating, an extractor hood above the oven, a water inlet for the steam system and, for gas models, a gas line.

We can send a technician to your site for installation and commissioning; travel and accommodation costs are covered by the buyer and can be included in the quotation. Within Türkiye, installation and commissioning are free of charge. Every oven is delivered with a user manual, and our team provides operator training during commissioning. After installation, we continue to provide technical support via WhatsApp, Telegram, email and video call, so you can reach us quickly whenever you need assistance.
