Standard applications compressors

The Diavia Standard Compressors Range has been specifically designed to be installed in any vehicle equipped with AC or Mobile Refrigeration Systems.
In addition to our home-made Harrison compressors, additional brand are available such as Sanden, Seiko Seiki and Tama.


HARRISON COMPRESSORS RANGE

HARRISON V5
The first volume-produced variable displacement compressor, the five-piston V-5 automatically adjusts displacement to match the vehicle’s air conditioning demand. A control valve in the V-5’s rear head senses evaporator load, and automatically changes displacement to match that load

HARRISON SP 10
These 10-cylinder fixed displacement compressors consist of fi ve double-ended pistons moving in the cylinder bores by a swash plate and shaft assembly. The 10 hemispherical shoes connect the pistons to the wash plate and shaft assembly. As the swash plate rotates, the shoes swivel, remaining in constant contact with the piston and the swash plate. The rotary motion of the swash plate is therefore converted to the reciprocating motion of the piston.

HARRISON SP 15
This compressor is provided with 10 pistons, and it has 154 cc displacement / revolution. The reliability level of this compressor is a high good level. The high number of pistons (10) is a guarantee of a less level of vibrations; the power consumption and the capacity curves are a very high level. The compressor body is provided with 8 “ears”; this characteristic , together with the mounting angle (+/- 90°), will let you good possibilities for the mounting. The compressors are available whether Rotalock ports (1” – 14 UNS), or O-Ring ports (3/4” 16 UNF ;7/8” 14 UNF) – see technical table.
The Harrison SP15 is interchangeable with the SD7H15 Sanden type.

HARRISON SP 21
This compressor is provided with 10 pistons, and it has 210 cc displacement / revolution. The reliability level of this compressor is a very good level, and its power and robustness are particularly suitable for commercial and industrial vehicles, tractors, etc. The high number of pistons (10) is a guarantee of a less level of vibrations and the capacity curves are a very high level. The compressor body is provided with flanged ports, but it’s possible to adapt the ports to O-Ring connections (3/4” 16 UNF; 7/8” 14 UNF) by means of two
adapters, supplied in the kits A03924 and A031056.

HARRISON CVC
The next generation of variable displacement piston compressor technology, Delphi’s Compact Variable Compressors (CVC), are based on a swash plate simple harmonic motion mechanism. The enhanced mechanism performance makes the CVC adaptable to both pneumatic and electronic controls.

HARRISON HD6
The HD6 compressor family is a six cylinder, axial-type compressor.

SEIKO SEIKI SS10 COMPRESSORS
These compressors have really light structure, compact size, flexible capacity control, generate very little noise, useful in the cases in which this characteristics is more important than the power. The quantity of oil in the refrigerant is very reduced, so the performances of the heat exchangers are completely used. These compressors use a vane rotary mechanism ; the displacement is calculated adding the single refrigerant volumes moved by the vane rotary mechanism during the suction phase – 1 turn of the rotor inside the compressor. This displacement is named “Equivalent displacement” In this catalogue you can find two types of displacement, 96cc for the compressors SS10 , and 121cc for the SS121.

SEIKO SEIKI SS121 COMPRESSORS

These compressors use a vane rotary mechanism ; the displacement is calculated adding the single refrigerant volumes moved by the vane rotary mechanism during the suction phase – 1 turn of the rotor inside the compressor. This displacement is named “Equivalent displacement”. In this catalogue you can fi nd two types of displacement, 96cc for the compressors SS10 , and 121cc for the SS121.

SANDEN SD7B10 COMPRESSORS
This compressor is provided with 7 pistons, and it has 99 cc displacement / revolution. The reliability level of this compressor is a very good level. The compressor body is provided with 4 “ears”; this characteristic , together with the mounting angle (+/- 90°), will let you good possibilities for the mounting. This SD7B10 compressor, is the version for R134a refrigerant, of the old type SD706 (for R12), so it has small dimensions and light weight (2,8 Kg) The compressors are available with flanged ports.

SANDEN SD7H15 COMPRESSORS
This compressor is provided with 7 pistons, and it has 154 cc displacement / revolution. The reliability level of this compressor is a very good level. The compressor body is provided with 8 “ears”; this characteristic , together with the mounting angle (+/- 90°), will let you good possibilities for the mounting. This SD7H15 compressor, is the version for R134a refrigerant, of the old type SD709 (for R12) The compressors are available with Rotalock ports ( 1” – 14 UNS), but also with O-Ring ports (3/4” 16 UNF ;7/8” 14 UNF) – see technical table.

SANDEN SD5H09 COMPRESSORS
This compressor is provided with 5 pistons, and it has (87 cc) displacement / revolution.
The reliability level of this compressor is a very good level. The compressor body is provided with 8 “ears”; this characteristic , together with the mounting angle (+/- 90°), will let you good possibilities for the mounting. This SD5H09 compressor, is the version for R134a. The compressors are available with O-Ring ports (3/4” 16 UNF ;7/8” 14 UNF) – see technical table.
