JOÃO RITO - EQUIPAMENTOS DE FRIO E DE CLIMATIZAÇÃO UNIPESSOAL LDA.

Small capacity condensing units, designed for small commercial applications such as convenience stores, petrol forecourts and cold rooms. Assembled with scroll or digital scroll compressors, designed for MT or LT applications. This model is built on a smallest condensing unit frame and provides a cooling capacity from 10kW to 30kW. Assembled with copper aluminium fin condenser, Copeland compressors with crankcase heater, high efficiency AC/EC axial fans and a liquid receiver. Built in a closed galvanized steel frame with polymer powder coating and additional insulation for silent unit operation. Electric panel includes phase rotation and phase loss monitoring relay, compressor and fan motor overheat protection, contactor and main switch. Additional assembly options are available.

The direct expansion system is popular due to easier installation and reduced system costs. Direct expansion ice banks are usually used for refrigeration of dairy products in medium or large farms, milk collection points, beer or milk factories. Refra manufactures ice banks based on this refrigeration model. Made with multiple stainless steel coil batteries, built into a large water reservoir, these systems work on the principle of ice formation. The refrigerant circulating in the coil batteries forces the formation of ice on the pipes, thus cooling the water inside the tank. This technology is capable of cooling particularly large amounts of water with relatively little energy consumption.

Refra manufactures liquid ice banks, designed for acumulation of capacity. Such units can be compatible with other refrigeration systems, if the hygienic standards of all units are ensured. The glycol used in the system is usually cooled by a separate chiller. Made with multiple stainless steel thermal coil batteries, built into a large water reservoir, these units work on the principle of ice formation. The glycol mixture circulating in the coil batteries forces the formation of ice on the pipes, thus cooling the water inside the tank. This technology is capable of cooling particularly large amounts of water with relatively little energy consumption.

Refra manufactures hot water tanks, tailored to various heating systems. With an operating pressure of 6 to 10 bar and the capacity of 300-3000 liters, these water storage and preparation tanks can help maintain the required amount of liquid for service continually and ensure a constant supply of hot water for comfortable consumption. Refra hot water tanks are available with an anti-legionella kit, which consists of a recirculation pump, heating element and timer. This kit prevents the spread of bacteria and is therefore particularly important for domestic water systems. A special 6 or 9 kW electric element can be added for additional water heating that will heat the water in the tank to the required temperature. The tank is made of carbon S235JR or 304/316L stainless steel, externally insulated with an additional (50-100mm) layer of polyurethane and lined with a high-quality red dermatine fabric. Both vertical and horizontal tank
