OSTRO V-TYPE DOUBLE-ROW CONDENSER

OSTRO V-TYPE DOUBLE-ROW CONDENSER OSTRO is the new V-type condenser for high power refrigeration, air conditioning and industrial processes. OSTRO can be configured in 3 solutions: Dry, Spray and Pad. In the Spray and Pad versions with water injection, the power increases are very significant and guarantee a legionnella-free solution. OSTRO can be used with a complete range of ventilations and refrigerants.

V-TYPE DOUBLE-ROW CONDENSER COIL In OSTRO series units, the coil dedicated to heat exchange during cooling is of the latest generation and adopts a geometry (tube and row spacing) that optimizes the exchange capacity in absolute terms, specific to ventilation absorption. The adoption of thick fins and the strong turbulence contribute to the remarkable heat exchange capacity of OSTRO units. All coils undergo hydraulic testing at 16 bar. STRUCTURE In the OSTRO series units, the air circulation is very effective thanks to the adoption of an exchange V that optimizes the aeraulics in the lower...

V-TYPE DOUBLE-ROW CONDENSER ADIABATIC SYSTEM The adiabatic system for Ostro units humidifies the intake air without spraying water directly on the coil: the air is then cooled before entering the heat exchanger, leading to a significant increase in the performance of the device. Metal or cellulose panels are installed in front of the coils, which initially absorb excess moisture and release it back into the air flowing through them. This dual-effect system guarantees high humidification rates and good protection of the heat exchanger fins. The recirculation system supplied reduces water...

Example of application of the ADIABATIC PAD on OSTRO L90 6p Improvements of system performances On the following conditions: Ambient T.35°C - E.G.35% DT10° Improvements of unit performances On the following conditions: Ambient T.35°C - E.G.35% DT10° • Condensation reduced by 7°C from ΔT1 10°C to ΔT1 3°C. • 100% increase of exchange capacity: 18 x 900 6P from 1 MW to 2 MW - 58 dB(A) 10m or • Reduced capacity consumption [on the same unit with EC motors + silencer]: minus 85% and minus 21dB(A). or • Space Saving ~ 55% and Money Saving ~15%: unit with 18 to 8 fans. • Chiller off for 2 more...
