In order to ensure that the cooler does not break, when the cooler is installed in the oil return circuit, it is necessary to install an explosion-proof valve or bypass unloading circuit. Recommend the best way to use: use another small pump, extract the oil tank internal heat supply cooler, so as to become an independent loop, see the "installation and maintenance" page.

COOLBIT has developed a special and exclusive structure
based on a deep research of fluid mechanics and an
optimization of its structure design. It has also employed
robots in welding and promoted its strength and metal fatigue
strength by more than 30% with its exclusive patent technology.
COOLBIT products have been completely approved by CE, even
including the connectors of electric appliances. Only those connectors
that conform to DIN regulations can be used in our products. Furthermore,
there are indicator lights signaling the working conditions of machineries.
COOLBIT is characterized by high reliability, stability and consideration.
There are a wide range of choices of high-standard fans to
satisfy different heat demands:
AC fans: with inside thermo-sensitive on-off switch,motors can
be protected from being damaged due to too high heat.
DC fans: with BLDC motors and protection level of IP68,the
fans will enjoy machinery longevity.
Coils of H level and structure design by Ball Bearing
Renowned electronic fan exported from Europe: with a
protection level of IP68, it is specially designed and produced
for different kinds of mobile equipments.
*Attention: the features above apply to different products. For detailed information, please consult us.
Compared with the traditional thermal cutting technology, the laser cutting
equipment usually adopts the computerized digital control technology
(CNC) device. With this device, the cutting data can be received from the
computer aided design (CAD) workstation using the telephone line. With
laser cutting, the laser cutting is narrow and the cutting seam is parallel to
both sides and perpendicular to the surface. The size accuracy of the
cutting parts can be up to + 0.05mm.
COOLBIT is the de facto standard wind cooler, relying on the deep in the air pressure and cooling technology experience, and the development of technical cooperation in Taiwan, successfully created a AH/AW/AL three series when the success and experience sharing to the world, see the vigorous development of the domestic air cooling technology for two years, COOLBIT prides just to draw the bone to the painted, copying imitation of god,The high stability and high reliability of the machine is our pursuit, one year warranty is only fundamental, five years of no fault operation is the design standard of COOLBIT.
1. I have been using water-cooling cooler, and will it be better to use the air-cooling machine?
Answer: the air-cooling technology has been developing rapidly, so that many problems such as the low efficiency of heat dissipation have been improved a lot. As the forerunner in the field, COOLBIT design air-cooling heat dissipation for thousands of machines. As a result, we are experienced in not only setting programs and product manufacture. All clients can choose our products without any doubts.
2. What about the quality guarantee of COOLBIT?
Answer: the warranty period of COOLBIT is 12 months, but it does not mean that our products can only be used for 12 months. Every single components and parts of our products are designed according to high standard and 12 months is the barest quality guarantee. Actually, all of our products are designed to satisfy the demand of five years’ use. For the past 20 years of market experiences, COOLBIT has enjoyed a high reputation for the high stability and reliability of its products.
