MiniZeas – LRMEQ3BY1

Overview

Daikin’s advanced inverter technologies are proven to significantly reduce energy costs. Considered best-in-class solutions for commercial refrigeration, Daikin refrigeration units are up to 50% more energy efficient than comparable units.

Product development has been shaped to deliver a good fit within urban locations, which are typified by their need for reliable, low noise, small footprint solutions.

In addition to the ease of installation built into the design of its products, Daikin prides itself on after-service, technical skills training and support materials available to its installers.  Central to this is its comprehensive portfolio, that includes the market-leading Conveni-Pack and ZEAS condensing units, the smallest yet on the market.

The Mini-ZEAS fills a gap in the field of urban commercial refrigeration. The operating range has the capacity to provide cooling at evaporating temperatures of -20 to +5. Highly reliable and extremely efficient, the whisper quiet ZEAS range is fast becoming the unit of choice for SME enterprises, such as local food retailers and petrol station forecourts as well as corner shops, that are typically situated in an urban environment.

In addition to severe local environmental requirements, such as reduction in actual noise emissions and “optical noise”, as well as building restrictions on outdoor installations, space is also an issue, with real estate costs at a premium.

Features

Refrigeration solution for small food retailers

  • Inverter technology guarantees optimal food conservation by ensuring an accurate temperature and humidity control
  • The economized scroll contributes to a longer lifetime expectation of the refrigeration equipment and less maintenance requirement
  • The use of R-410A refrigerant allows the use of smaller pipping diameters, thus reducing the refrigerant content in the system helping to lower our CO2 footprint . R-410A is fully compliant with the latest F-Gas regulation and can be still used after 2020 and beyond
  • The DC economized compressor improves drastically the efficiency of the unit, thus helps lowering the energy bill!
  • Lowest sound level in the market down to 31 dBA. Sound level can be even further reduced thanks to the low noise modes
  • The weight of the unit is very low, therefore the unit can even be mounted on the wall
  • Up to 75% smaller than equivalent products in the market, ideal for those places where space is limited
  • Advanced software solution for easy system configuration and commissioning
