YOJO Heat Exchanger Advantage:
High Efficiency
The embossed pattern of the YOJO's special heat transfer plates promotes high turbulence at low fluid velocities. The high turbulence results in very high heat transfer coefficients.
Compact Size
YOJO's brazed heat exchanger can be anywhere from 50% to 80% smaller than other types of heat exchangers. It requires less floor space due to the high thermal efficiency of the stainless steel. The plates are brazed together at high temperatures, allowing the heat exchanger to be compact, leak tight, and rugged.
Close Approach Temperatures
Close-approach temperatures of 1-2°F (0.5-1.0°C) are possible because of true counter flow and high heat transfer efficiency of the plates. This is an important factor in regeneration and heat recovery processes.
High Temperature and Pressure Ratings
YOJO's Brazed Plate Heat Exchanger maximum working pressures from 300 psi to 650 psi, and temperature ratings of 350°F.
Brazed Plate Heat Exchanger
High efficiency heat exchanger
Our ZL20, ZL62 series, ZL130, ZL250 are specifically developed for R410A refrigerant, which is ideal alternative of R22. R410A efficient heat exchanger is not only resistant to high pressure, but also with less refrigerant to achieve the same cooling effect. ZL20 and ZL62 are unilateral flow. ZL130 and ZL250 are diagonal flow. They can work from the power range of 1KW to 250KW.
Aircross
Aircross is a cross flow plate heat exchanger vacuume with pure copper or nickel based material. The top and bottom plates including side A connections are brazed to the plate package. This model can be asymmentrical for 1) applications with a smaller flow rate at high pressure on the one side ( Side A), and a larger flow rate at with lower pressure on the other ( Side B): different sizes for the connections In and Out, different channel lengths, different channel areas and volumes; 2) applications with a constant and defined gas flow on one side and medium with higher density on the other side. Normally YOJO-AirCross is used with a liquid on side A and gas on side B.
