PRODUCTION PROGRAMME:

• Refrigeration systems and condensing units. According to investor demands we design, manufacture and install refrigeration systems and condensing units for all temperature regimes.
• Refrigerated warehouses and cold storage rooms. Sena designs and builds refrigerated warehouses and cold storage rooms of different sizes and capacities. Depending on clients specifications our team of experienced engineers designs refrigerated warehouses, according to purpose of storage, capacity and type of the product, number and type of cold storage rooms, as well as other construction and location conditions. Completed and fully functional facility is delivered to the client according to the “turnkey” principle. Cold storage rooms are built for positive, negative and combined temperature regimes, depending on cooling requirements.
• Deep freeze tunnels (circulating and batch). We design, manufacture and install deep freeze tunnels, so called Shock chambers for different freezing capacities. They are intended for all types of goods, and with an optimized design of air flow they achieve maximum freezing efficiency. These deep freeze tunnels provide quick and even freeze of the products, without damage and with preservation of the quality.
• Refrigeration systems for indirect cooling - Chillers. We offer refrigeration systems for indirect cooling, Chillers, that provide circulating cooling of fluids for different technological processes.
• Cold rooms with controlled atmosphere – ULO cold storage with DCA technology.  ULO (Ultra Low Oxygen) cold storage rooms, with DCA (Dynamic Controlled Atmosphere) technology are intended for prolonged storage of fruits and vegetables. These cold rooms provide high-quality and long storage of products with the use of fine temperature regulation, humidity and composition of gases in the cold room. Fruits and vegetables in ULO cold storage can be stored up to 2-4 times longer than in other cooling conditions.
• Refrigeration (thermoinsulated) doors. We also offer hinged, sliding and sectional thermoinsulated doors of all sizes for panel and wall mounting, as well as doors for special purposes. All sliding and sectional doors can be delivered and mounted with an automatic control system.
• Thermalinsulated panels. Sena offers thermalinsulated (sandwich) panels with excellent thermal-insulation properties. Sandwich panels are coated with galvanized and plasticized metal sheet, and are made with a PUR, PIR and a mineral wool filling. These panels are used for construction of cold storage warehouses, cold rooms, meat processing plants, dairy plants and other cidustrial and commercial buildings.
• Products for baking industry. Sena designs and manufactures Shock (spiral) tunnels for dough freezing, as well as chambers for dough fermenting used in the baking industry.
• Pools for „Ice water“. An integral part of equipment in milk processing technology.
