手術
Recold’s JW Fluid Cooler utilizes the efficiency of evaporative cooling, along with the superior corrosion and heat transfer characteristics of copper to efficiently cool process fluid while protecting is from the possibility of contamination. Hot process fluid travels through the inside of the copper coil as cold water is sprayed over the exterior of the coil.
Fresh air is forced up through the exterior of the coil while cold water is sprayed down over the coil in an efficient counterflow arrangement. Heat from the process fluid is transferred to the spray water reducing the temperature of the process liquid. Heat from the spray water is discharged through the atmosphere through evaporation of the spray water.
The Recold JW is a low noise, forced draft, centrifugal fan design with a weight saving, corrosion free copper coil all in a low height configuration. This Evaporative Fluid Cooler is a ruggedly built unit constructed to provide many years of durable, dependable service with minimal maintenance requirements. Its low profile design simplifies integration into architectural designs and can be placed indoors. Quality materials and workmanship are a key factor in meeting this objective. All units are completely factory assembled and tested to ensure a quick and easy installation with no startup problems.
銅熱盤管
Recold’s copper coils offer the advantage of superior corrosion resistance at an affordable price. The copper coil surface provides a barrier from the corrosive effects of a warm, wet environment. Other manufacturers use materials that are heavier and more prone to corrosion. Copper coils are 30 to 40 percent lighter than comparable galvanized steel coils.
Combining Recold’s 5/8” diameter tube with copper’s high thermal conductivity characteristics provides for far better heat transfer properties than heavy wall galvanized steel. In the event of coil damage, copper can be easily repaired with Recold’s optional external header, while galvanized steel coils are almost impossible to repair.
Coil tube bundle is constructed of 5/8”O.D. copper tubing with stainless steel tube sheets and copper headers. The copper construction offers a noncorrosive coil for extended service life. The high quality virgin copper tube conforms with the highest standards in quality control to guard against pitting and defects.
卓越的結構
The Recold J series uses Stainless Steel Collection Basins as a standard on all models. All collection basin parts exposed to the circulating water including attaching hardware and all basin options are heavy-gauge series 300 stainless steel. Additionally, all internal structural members are fabricated from 300 series stainless steel. The balance of the tower components, casing and mechanical support are fabricated from heavy mill galvanized steel.
All tower components are mounted on a rigid steel skid allowing unparalleled stability and easy installation. Optional components such as pump stations or tower controls are also mounted on the skid as well, reducing costly field assembly labor hours for these ancillary systems.
水循環系統
水循環泵是一種緊密耦合、青銅安裝的離心式機械密封泵。每個泵浦均在工廠安裝並透過管道連接。標準電機為開放式防滴電機，適合戶外使用。循環水直接透過管道輸送到盤管上，盤管利用新鮮空氣流和噴水透過蒸發冷卻來排出熱量。沒有填充介質會弄髒或清潔。
水妝
Recold 獨特的補水由實心黃銅浮閥提供，浮球臂和浮球安裝在外部浮箱中。這樣可以實現穩定、無故障的運行，輕鬆觀察水位運行情況並在設備運行時維護閥門。
風扇部分
離心式風扇向前彎曲，經靜態和動態平衡，由鍍鋅鋼製成。風扇外殼具有彎曲的入口環，可有效地使空氣進入和排出到盤中。前彎離心式風扇以低轉速運轉，運轉安靜，使用壽命長。
風扇安裝在堅固的鋼軸上，並塗上抗腐蝕塗層。重型軸台型自調心球軸承位於風扇軸的兩端。延長的潤滑管路作為標準設備提供，以便在不拆卸風扇護罩的情況下維修軸承。
風扇馬達
標準配備的風扇馬達為開放式防滴型，適合戶外使用。馬達的服務係數為 1.15，安裝在易於操作的重型可調式底座上。作為標準配置，裝置使用適合戶外使用的節能 NEMA 框架 ODP 風扇馬達。
風扇防護罩
所有移動部件均採用 OSHA 批准的鍍鋅鋼絲網進行保護。每個防護罩均可輕鬆拆除，以便檢修風扇。
漂移消除器
除水器由 PVC 組件製成，部分可拆卸且易於操作。每個部分均採用三斷口設計，可實現氣流的三種變化，深度約為 5 英寸。使用耐用的 PVC 消除了與鍍鋅消除器相關的腐蝕問題。
檢修門
大型矩形檢修門的位置經過精心設計，可通往上部配水系統和下部盤盆。專利的門無需使用墊圈或緊固件即可提供完整的氣密和水密密封。
萬一循環幫浦故障，蒸發冷凝器容量會驟降至設計容量的 10-20% 之間。 Recold 開發了一種可選的緊急離散噴霧系統，可自動從標準噴霧系統切換到緊急系統，在設計條件下提供約 85-90% 的容量，同時維修/更換泵浦。
雙風扇馬達系統
對於注重能源並需要備用功能的用戶，Recold J 系列裝置還提供 Recold 可選雙風扇馬達系統，該系統將標準全容量馬達與更小的馬達結合在一起。較低速風扇馬達將提供 65-70% 之間的設計容量，功率約為 1/8 匹馬力。當主馬達發生故障時，此輔助馬達也可用作備用馬達。當丟失一個單位導致肉變質和冰淇淋融化時，這是必要的。運轉低速風扇馬達可顯著降低 dB 噪音，非常適合噪音敏感場所。
控制系統
Recold can accommodate control systems ranging in sophistacation from standard fan starts and disconnects to Programmable Logic Controllers that work in conjunction with your building or process system. Control options such as variable speed drives provides the ultimate in temperature control, energy management, sound control and mechanical equipment longevity. Solid State water level controls monitor basin water level with solenoid-valve water makeup. Configurations include makeup along with high and low water level alarm and cutoff and electric basin heater cutoff. Consult your local representative for Recold’s extensive array of controls.
