Orientation in the stocked MHI equipment: Kazan and Kazan Arctic wall-mounted heat-pump sets (SRK indoor / SRC outdoor), SCM multi-split outdoor units, the ducted and cassette FD families (FDU/FDUM/FDT/FDTC/FDE/FDF), R32 practice and the panels and filter kits that complete an installation.
The Nordic-market Kazan series pairs an SRK wall-mounted indoor with its SRC outdoor unit, tuned for heating performance in cold climates; Kazan Arctic is the low-ambient line. Stocked examples: SRK20ZTX-WA (Arctic 7600 indoor), SRK35ZTX-WA (Arctic 8000 indoor), outdoor SRC20ZSX-W (Kazan 5.5) and SRC35ZSX-WA (Kazan 6.8). Indoor and outdoor are a matched pair — order both halves of the same set; capacity names (5.5/6.8/7600/8000) are the series' market designations, with engineering data in the MHI tables per pair.
One SCM outdoor drives two to several indoors of mixed type: SCM40ZS-W (class 6.3), SCM50ZS-W (7.5), SCM80ZS-W (9.8), all R32. Combination rules (which indoor sizes, total index, line lengths per branch) come from MHI's combination table for the exact SCM model — hold the installation to it; multi-splits forgive neither overconnection nor undersized branch piping.
| Family | Form | Stocked examples |
|---|---|---|
| FDC | Commercial outdoor (PAC) | FDC100VSX-W, FDC125VSX-W, FDC140VSX-W |
| FDU / FDUM | High-static (200 Pa) / medium-static (100 Pa) duct | FDUM60VH (6.3 kW) |
| FDT / FDTC | 4-way cassette / compact cassette | panels below |
| FDE / FDF / SRR | Ceiling-suspended / floor / slim duct | SRR35ZS-W Kakusu duct, SRR50ZS-W |
Cassettes ship without their face: order the decoration panel for the family — TC-PSA-5AW-E for FDTC (VG/VH), TPSA5AWE for FDT, Airflex frame — and consumables like duct-unit filter kits (UM-FL1EF for FDUM 50 VF).
