Hydraulic oil cooler Description Heat exchangers are used to exchange heat between two fluids. Plate heat exchangers are high performance components and provide a high level of efficiency combined with compact dimensions and low weight. Their efficiency reduces the amount of cooling water required for heat transfer which results in low operating costs. Features Plates and connections are manufactured from stainless steel to AISI 316, vacuum brazed with cooper. The special moulding of the plates produces the turbulent flow necessary for effective heat transfer and provides the plate heat exchanger with a high level of mechanical strength. Operating Details Medium: Water glycol HFC operating fluids Water Oil Contamination The quantity of particles in suspension should be less than 10 mg/l, particle size <0.6mm Thread like particles cause a rapid rise in pressure drops. Temperature range: 10C to 225C (freezing point and boiling point must be taken into consideration) Pressure: Max 45 bar up to 225C, testing pressure 60 bar. Corrosion The following limits refer to a pH value of 7 Free chlorine. CL2<0.5ppm Chloride ions CL <700 ppm at 20C <200 ppm at 50C Other limits PH7-10 SULPHATE so4 2-<100 ppm [HCO3]/[SO4 2-]>1 Ammonia, NH3< 10 ppm Free co< 10 ppm The following irons are not corrosive under normal conditions: Phosphate, nitrate, nitrite, iron, manganese, sodium and potassium Application Hydraulic oil cooling, Electricity and cogeneration applications, marine oil cooling, turbine engine oil cooler, automotive, construction, railways, steel industry Model BL14 BL20 BL26 BL26C BL50 BL95 Width, A [mm] 78 76 111 124 111 191 Height, B [mm] 206 310 310 304 525 616 Length, E [mm] 9+2.3n 9+2.3n 10+2.36n 13+2.4n 10+2.35n 11+2.35n Horizontal port distance, C [mm] 42 42 50 70 50 92 Vertical port distance, D [mm] 172 282 250 250 466 519 Max pressure [Mpa] 3 3 3 3/4.5 3/4.5 3/4.5 Max flowrate [M3/h] 3.6 3.6 8.1 8.1 12.7 39 Weight [kg] 0.6+0.06n 1.0+0.08n 1.3+0.12n 2.2+0.16n 2.6+0.19n 7.8+0.36n Model BL120 BL190 BL200 BL1400 BL100 * BL200 * Width, A [mm] 246 307 321 429 248 322 Height, B [mm] 528 696 738 1398 495 739 Length, E [mm] 13+2.36n 13+2.75n 13+2.7n 22+2.78n 10+2.15n 13+2.55n Horizontal port distance, C [mm] 174 179 188 220 157 205.2 Vertical port distance, D [mm] 456 567 603 1190 405 631 Max pressure [Mpa] 3 3 2.1 1.5 3/4.5 3/4.5 Max flowrate [M3/h] 42 100 100 300 42 100 Weight [kg] 7.2+0.52n 12.5+0.72n 13+0.75n 31.8+1.73n 6.5+0.37n 13+0.78n
