Ventilation:
Effective ventilation is critical to keep appropriate parameters for humans inside buildings and for the technological processes. During its 30 years of operation H&M designed new ventilation systems and optimized existing ones for typical and highly demanding objects (from modern shopping malls to firearms/ ammunition manufacturing plants). Our office offers comprehensive design support, including the execution of construction projects (allowing for obtaining a building permit) for all kind of ventilation systems, including:
- industrial ventilation,
- technological ventilation,
- ventilation of public utility buildings,
- ventilation of residential buildings,
- smoke and fire ventilation.
In addition, we can optimize existing solutions to minimize their energy consumption, selecting most effective energy recovery system and implementation of anti-frost protection.
Our offer also includes full construction site supervision.
Air conditioning and refrigeration:
Air conditioning (AC) is used more often every year in order to maintain the comfortable conditions during summer season. Moreover, cooling systems are critical for the proper operation of many technological processes. AC systems are characterized by very high energy consumption. Due to this fact, precise selection of appropriate devices and system components is necessary to reduce the operational costs. H&M has extensive experience in designing of refrigeration and air conditioning systems, ranging from standard VRF / VRV systems to cryogenic cooling systems for power plants. As part of our services, we offer full design support for:
- chilled water systems,
- freon systems (VRF / VRV),
- ammonia systems,
- absorption/adsorption systems.
In addition, we offer dedicated cooling solutions for specific objects and our own air-conditioning technologies based on renewable energy.
Our offer also includes full construction site supervision.
Heating systems:
Heating systems are responsible for over half of the energy consumption in buildings located in Central and North Europe, therefore it is highly important to design them correctly. We offer full design support for advanced heating and district heating systems. We design both standard heating systems for residential buildings and complex technological solutions for industry. Our offer includes (but it is not limited to):
- standard heating systems (radiator, surface and air heating systems),
- technological heating systems (water/ glycol/ steam other media),
- district heating,
- selection and optimization of the operation of the heat source,
- designing district heating substations, heat pumping stations and boiler rooms (natural gas/oil/coal).
In addition, we offer dedicated solutions for specific objects and our own technologies based on renewable energy. Our offer also includes full construction site supervision.
Water and sewage systems:
H&M offers full support in water and sewage systems design. We develop complete designs for both standard projects (internal systems and external grids) and complex, custom solutions (e.g. energy recovery from wastewater). Our offer includes (but it is not limited to):
- internal sewage systems,
- internal water systems,
- external water and sewage grids,
- selection and optimization of the hot water heating system,
- energy recovery systems.
In addition, our offer includes optimization of existing water and sewage systems. Our offer also includes full construction site supervision.
Gas systems:
Our offer includes complete support in gas systems design. We design typical natural gas systems and non-standard gas systems (medical gases, technical gases, compressed air, etc.). Our offer includes (but it is not limited to):
- internal natural gas systems (NG, ANG, CNG, LNG),
- natural gas grids,
- compressed air systems,
- medical gas systems,
- technical gas systems.
In addition, our offer includes optimization of existing gas systems. Our offer also includes full construction site supervision.
External grids:
H&M offers full design support in the field of external grids, including district heating and cooling systems, water and sewage (water and sanitary sewers systems, rainwater sewers), natural gas and other solutions. Our offer includes (but it is not limited to):
- district heating,
- water grids,
- sanitary and rainwater sewers,
- natural gas pipelines,
- drainage of rainwater,
- ground source heat pump systems.
Our offer also includes full construction site supervision.
Dedicated solutions:
Due to their specific nature, many objects require dedicated, custom-made solutions. For example, this may apply to industrial facilities with large amount of waste heat that can recovered. Another example may be technological process which requires high amount of fresh air, but cannot use standard energy recovery methods in the treatment system. During over thirty years of our presence on the market, we have developed a number of dedicated solutions for demanding objects (from dedicated anti-frost systems for recuperators in spray booths to energy recovery from copper mine intake shafts). Regardless of the problem, we are able to propose and supervise the implementation of a solution that will significantly reduce the energy consumption of any object or process
