ＭＤＩ Product Lineup

The "BLACKBOX" is a compact water heat source heat pump (water-cooled chiller) that is very advantageous for handling on-site due to its small size and lightweight. Internally, it is designed to thoroughly avoid failures by eliminating four-way valves, allowing for cold and hot water output without switching (controlled on the piping side as needed). To minimize on-site costs, the refrigerant gas pathway is kept to a minimum, making it easy for equipment construction companies unfamiliar with refrigeration units to install. 【Features】 ■ The number of necessary parts, size, weight, and operational stability vary greatly. ■ All on-site costs can be reduced, resulting in significantly different total costs. ■ Reduces weight load in architectural design. ■ Suitable size for extremely small spaces. ■ Multiple units can be installed. *For more details, please refer to the PDF materials or feel free to contact us.

The MDI simple heat pump chiller is a hybrid heat source chiller designed to accommodate various environments, including soil temperature control for vinyl houses, hot spring heating, foot baths, air conditioning, boiler feed water heating, and heat sources from pure water, seawater, wastewater, air, and geothermal sources. It is suitable for a wide range of applications, from general households to farms, food plants, and factories. It can also handle wastewater, seawater, and corrosive liquids with various optional heat exchangers. It is designed to be adaptable to any environment and is a modern unit that allows for easy installation of multiple small units. === Design Concept === Not just a heat pump... ● Utilizes a plate-type heat exchanger specifically designed for new refrigerant gases with an ultra-large heat transfer area ● Simple installation that anyone can handle, with just one switch (for cold water/hot water) ● Designed to achieve significant energy savings during full operation ● Capable of switching between cold water and hot water ● Can be combined with special heat exchangers that utilize any heat source

We propose energy-saving measures using heat exchangers for waste heat recovery. We contribute to the reduction of CO2 emissions and energy consumption across a wide range of industries and fields. We also have products that can be introduced in environments where oil mist and VOCs are generated. Please feel free to consult us. ★ We are distributing a collection of case studies. You can view it immediately via "PDF Download." 【Featured Cases (Excerpt)】 ■ Achieved clean exhaust by reducing exhaust heat temperature and removing oil mist ■ VOC measures and heat recovery in a drying oven at a painting factory ■ Utilized exhaust heat from the furnace for a steam unit heater, reducing heating costs ■ Used exhaust heat from boiler blowdown water to preheat feed water ■ Combined two heat exchangers to thoroughly recover heat from low-temperature steam, etc. * For more information on waste heat recovery and energy saving, please feel free to contact us.

At MDI, we handle various energy-saving devices, including plate heat exchangers, as well as cleaning solutions. From energy-saving consulting to after-sales maintenance, we consistently provide high-quality services to our customers. In the "Waste Heat Recovery Case Studies," we introduce examples of geothermal heat utilization heat pumps and compare them with fecal waste heat utilization heat pumps. For any inquiries or consultations regarding waste heat recovery and energy saving, please feel free to contact us. **Benefits of Fecal Waste Heat Utilization** - No excavation costs or long-distance tubing required - Achieves lower costs - Provides heat at much higher temperatures than geothermal heat, with minimal heat loss - Conductive heat and radiant heat effects for floor heating and cooling *For more details, please refer to the PDF materials or feel free to contact us.*
