Compact, Inexpensive, Automatic System to Deliver Water at AlternatingTemperatures for Hatchery Studies

摘要

A system was developed to supply ambient and heated water to incubator trays atvaried time intervals. Space, budget, and personnel constraints necessitated the development of a compact and inexpensive design that functioned independently for up to 7 d. The system consists of a programmable control panel, solenoid valves that control the flow of water into incubator stacks, and two 189-L electric water heaters plumbed in series.
