Emmegi Coolers
Overheating ranks No.2 in the list of most common problems for hydraulic equipment and Emmegi Air Blast Hydraulic Oil Coolers are an excellent product to help combat this problem.
Emmegi air-oil heat exchangers are used for cooling oil hydraulic systems, using the coolant ambient air that passes over the radiant by means of a fan operated by an electric or hydraulic motor. The cooler element, in high resistance aluminium alloy, is obtained by means of a braze-welding process carried out under vacuum. The particular configuration of the cooling pipes increases the turbulence of the fluid consequently of the exchange capacity; moreover, the presence of special jets on the cooler finning further improves the total transmission coefficient. The result is a very small, light and robust technologically advanced product.
This includes the Emmegi 12V DC 2010K Air Blast Cooler, 12V DC 2015K Air Blast Cooler, 12v 2020K Air Blast Cooler, 12V DC 2030K Air Blast Cooler, 12V DC 2040K Air Blast Cooler and the 12V DC 2050K Air Blast Cooler. Including the Emmegi 12V DC MS1 Mobile-S Air-Oil Cooler and the 12 V DC MS2 Mobile-S Air-Oil Cooler.
We also stock the 24V DC 2010K Air Blast Cooler, 2015K Air Blast Cooler, 2020K Air Blast Cooler, 2024K Air-Oil Cooler, 2030K Air Blast Cooler, 2040K Air Blast Cooler and the 2050K Air Blast Cooler. Including the Emmegi 24V DC MS1 Mobile-S-Air-Oil Cooler and the 24V DC MS2 Mobile-S Air-Oil Cooler.
What are Air Blast Coolers Used for?
Air blast coolers are used for process cooling. Ambient air is forced over a heat exchanger to remove unwanted heat from a closed circuit containing process fluids or intermediate coolant. Coolant return temperatures can be as low as 10°C above ambient air.
Why use an Emmegi Air Blast Hydraulic Oil Cooler?
As stated at the beginning, overheating ranks No.2 in the list of most common problems with hydraulic equipment. Leaks being No.1.
As a means of power transmission, hydraulics has many advantages. But overall efficiency is NOT one of them. A single-reduction gearbox has an efficiency of 98 to 99 percent, double-reduction 96 to 97 percent and triple- reduction 95 percent. A chain drive in good condition has an efficiency of 97 to 98 percent.
A high-performance piston pump has an efficiency of 92%. If this pump drives a piston motor, the overall efficiency of this hydraulic drive is 85% (0.92 x 0.92 x 100 = 85) and this is without considering losses through valves and conductors.
And that's good! A gear pump or motor in good condition is 85 percent efficient. So, a gear pump driving a gear motor has a best-case efficiency of 0.85 x 0.85 = 0.72. That's 72 percent - not considering losses through valves and conductors.
What this tells us is that every hydraulic system with a high, continuous power input (and therefore output power) requires an oil cooler to keep oil temperature stable and within acceptable limits.
