Sintez TMK offers comprehensive services for the design, installation, maintenance and repair of ammonia-free industrial refrigeration equipment.
Types of refrigeration equipment
Industrial refrigeration machines and installations serve to reduce and maintain temperature within a given range. As a rule, we are talking about the temperature difference with the environment from 10 degrees. Equipment that allows cooling below minus 153 degrees Celsius is no longer called refrigeration, but cryogenic, work with it requires special tolerances.
Industrial refrigeration units are necessarily carried out according to the design task, which includes information about what needs to be cooled, how cooled, and what.
Refrigeration units consist of one or more refrigeration machines, which include: water, gas and energy supply systems, control equipment, control and measuring equipment, and a heat exchange system with a cooled object. Refrigeration equipment is installed both indoors and outdoors, as well as on transport (road, rail, river or sea). In addition to the cooling function, refrigeration equipment can also be used to reduce indoor humidity.
Each of the refrigeration units has its own design and functional features, dictated, among other things, by the scope of their application. Sintez TMK offers comprehensive installation services refrigeration equipment, as well as design, maintenance and repair for industrial enterprises (for example, welding sites), medical institutions, meat and dairy enterprises, warehouses, chemical industries, as well as for refrigerated vessels. Performing the installation of refrigeration equipment, specialists carry out the installation and connection of engineering power supply systems, supply and discharge pipelines, the supply, exhaust and circulation ventilation system.
The most efficient and productive type of industrial refrigeration equipment at present are chillers – refrigeration machines with an intermediate coolant, which is supplied to fan coils or other heat exchangers through a system of pipelines. Chillers have internal and external blocks. Internal – evaporators are thin coils through which freon (for example) of low pressure circulates. The coil cools the water, which then flows to the fan coils and central air conditioners. External units – capacitors – release heat from anywhere into the atmosphere.
By the type of their device chillers are divided into air and liquid. In the first case, the capacitors are cooled by an incoming stream of air, in the second – by a liquid (usually not freezing). Despite the presence of additional elements (such as a cooling tower, for example), the more stringent requirements for installation (ventilator, basement or other specially allocated space) increased complexity and cost, it is such industrial cooling systems that have recently become more common (mainly due to relatively small dimensions and high productivity).
Preparatory stage of installation
The preparatory stage for the installation of industrial refrigeration equipment consists in studying the drawings of industrial facilities, passports of refrigeration equipment, factory instructions and technical conditions. Also, before the start of installation, the specialists of Sintez TMK perform the development of RPR, the laying of supply networks and pipelines.
Due to the significant weight, dimensions of the units and units, the installation of industrial refrigeration equipment, as well as all previous work, must be carried out in strict accordance with the provisions specified in the technical documentation of the equipment manufacturer. Technical specifications (TU) for connection to intra-workshop engineering networks, the project of their placement, as well as updated editions of the relevant GOST, SNIP, JV and other regulatory documents.
Equipment and equipment for installation
The efficiency and speed of installation of industrial refrigeration equipment is largely determined by the special equipment and means of mechanization used for the implementation of work and in particular: used mounting cranes, portal systems, lifting mechanisms, loaders. The choice of a particular device or crane depends on the geometric dimensions, weight and design location of the equipment. As a rule, for the installation of industrial refrigeration equipment, automobile cranes with a carrying capacity of about 25 tons and a boom departure of up to 22 meters are used. The exact parameters of the crane are determined in the PPR.
Installation of refrigeration equipment
Installation of refrigeration equipment includes the following operations (on the example of a chiller, enlarged): delivery of a chiller, installation and installation of supply networks and pipelines (including those that connect the internal and external chiller unit), marking of the equipment placement, lifting and installing a chiller, connecting a chiller, tying a chiller on water, installation of a hydromodule, installation and configuration of automatic control systems, testing, commissioning of a chiller, delivery of equipment to the customer. The cost of work is strictly individual, but always justified by calculations.
Refrigeration equipment
Industrial refrigeration units are technically complex devices that require regular maintenance and supervision. Qualified technicians are required to perform these functions. Proper and timely maintenance of industrial refrigeration equipment protects it from breakdowns and prolongs the resource. If these simple conditions are met, the uptime of an industrial chiller can be 20 years or more.
Sintez TMK offers comprehensive maintenance and repair services for ammonia-free industrial refrigeration equipment. The list of mandatory and additional maintenance works for refrigeration equipment includes the following operations: general inspection of units and units, inspection of the air condenser; checking the tightness of the freon circuit and elimination of leaks; checking the evaporator and the integrity of the thermal insulation; checking the safety and control devices supplying the voltage, as well as the starting and operating currents of the compressor; monitoring the noise level of the compressor; cleaning or replacing filters; removing moisture from the circuit of the cooling system; purging with air, washing with ethylene glycol; checking the TEN and evapter.
Why us?
Sintez TMK has a unique experience in carrying out works on installation of industrial refrigeration equipment in a short time in the conditions of existing production. The portfolio of our company includes successfully completed projects at industrial enterprises (cooling in welding shops), meat and dairy production, large warehouse complexes. By ordering the service of installation, refrigeration equipment in our company, you are guaranteed to receive high-quality service and save yourself from the need to eliminate the consequences of an unprofessional attitude to the case. Errors when installing industrial refrigeration equipment and neglecting its regular maintenance can lead to a leak of refrigerant (freon) from highways, failure of the compressor, getting moisture into the refrigeration circuit, which in turn is likely to lead to a long stop of equipment and significant financial losses.
