Checked October 2026 on the investor's budget question. New
docs/suppliers/china-utilities.md: boiler makers (ZOZEN, Sitong,
Fangkuai, Taiguo, Yuanda, Yongxing, Taishan, Nobeth) with fit for 500
kg/h at 1.25 MPa, claimed certificates, Thai references and listing
prices; the Thai rules for an imported boiler (MR and MOI notification
B.E. 2549: ASME/JIS/EN or equivalent, certification-body verification,
once-through relief does not reach 10.5 bar, licensed controller, annual
inspection); compressor makers with Thai offices (Kaishan, Denair) and
sizing; hydraulic pump sets and accumulators (Huade, Yuci, Hengli, WMD,
Renowell, Inovance, NXQ makers), the shared-ring-main risks and Thai HPU
builders; duty and freight; open RFQs.
Result: about 2M THB at the midpoint (~2.5M with contingency), ~1 % of
the 216M target, mostly the boilers; Newbilt aggregates stay Newbilt's.
total-investment notes it and lists the uncosted central hydraulic
plant; utilities CSV gets the Chinese candidates and route estimates;
backlinks from equipment-suppliers, pressing-line, README.
