Reasons to choose our EWA/FD/H/S-TZ D
Daikin Single- Screw Compressor design.
The Daikin single screw compressor design. This type of technology is designed to be extremely reliable, even in harsh environments.
Outstanding reliability ensured by Daikin’s in-house Inverter
Two separate and independent refrigerant circuits ensuring maximum
safety and ease of maintenance The cooling for the inverter is thorough refrigerant also with independent cooling lines for higher reliability.
Cutting-edge efficiency thanks to Daikin’s in-house VFD & Variable Volume Ratio.
Daikin VFD allows the unit to operate optimally, reducing and controlling running costs in every working condition. The in-house single-screw compressor is integrated with the Variable Volume Ratio (VVR), which
modulates the compression ratio enhancing the efficiency of the compressor with varying ambient conditions with varying ambient conditions based on the 4 efficiency tiers offered: Blue (B-), Silver (S-), Gold (X-), and Platinum (P-).
Integrated Active Harmonic Filter by Daikin.
Despite the free-cooling mode, Daikin TZ D units are extremely
compact. This is due to a special redesign of the condenser
section, which not only reduces the space required but also
improves the overall efficiency of the system.
Space-Efficient Free Cooling
Free cooling configuration does not require any
additional space, so they do not take up any extra
space compared to a standard chiller without free
cooling capability.
Wide operating envelope.
The TZ D units can operate in a wide range of conditions, making them suitable for a variety of applications. They can provide chilled water for applications such as ice rinks with temperatures as low as -15°C, while also being suitable for data centers that require higher evaporator outlet temperatures of up to 30°C. This versatility provides exceptional flexibility, allowing TZ D units to operate effectively in a wide range of
environments and climates.
Free Cooling Configurations
Open Loop (with glycol)
Free cooling system is designed to chill the fluid by using cold energy from the environment. When outdoor ambient is above fluid temperature the unit provides the cooling capacity using only the compressors (Mechanical cooling mode). When the ambient temperature drops below the temperature of the fluid entering the unit, outdoor air can be used to chill the fluid before it reaches the evaporator, moving from partial to Full free cooling according to ambient temperature variation.
Closed Loop (without glycol)
The unit’s brazed plate heat exchanger create a closed loop with the free cooling exchanger and a dedicated pump. In this system the glycol is confined in the closed loop.
The glycol free option operates with a “closed loop” system, providing a compliant and efficient solution for applications where avoiding the use of glycol is preferred.
Among its benefits, it can lead to significant cost savings as the avoidance of glycol in the customer’s system makes it easier to maintain and improve overall efficiency. In
industrial processes, it reduces the risk of contamination, ensuring that product quality is not compromised.
