typically 2,000 to 8,000 square feet, located within dense urban areas. Unlike a conventional retail store or distribution centre, it has no customer-facing area. Its sole purpose is to receive stock, store it across ambient, chilled, and frozen zones, and dispatch picker-packed orders to delivery riders within minutes.<\/span><\/p><p><span style=\"font-weight: 400;\">Blinkit, Zepto, Swiggy Instamart, and BigBasket Now collectively operate thousands of these stores across Indian cities, with the total count expected to cross 8,000 by 2027. Speed and product quality are the two pillars of the business model. Both are threatened by heat.<\/span><\/p><p><span style=\"font-weight: 400;\">When ambient zone temperatures in a dark store exceed 28 degrees Celsius during Indian summer, packaged goods deteriorate faster, cardboard packaging weakens and deforms, and the pickers working in tight aisles slow down significantly due to heat fatigue. An order that sits in a 35-degree dark store for 30 minutes before dispatch arrives in compromised condition. One bad experience is enough to lose a customer permanently.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-36c492f e-flex e-con-boxed e-con e-parent\" data-id=\"36c492f\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-3fbd2d3 elementor-widget elementor-widget-heading\" data-id=\"3fbd2d3\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\"><span class=\"ez-toc-section\" id=\"What_Temperature_and_Humidity_Levels_Does_an_Ambient_Zone_Need\"><\/span>What Temperature and Humidity Levels Does an Ambient Zone Need?<span class=\"ez-toc-section-end\"><\/span><\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-17f633b elementor-widget elementor-widget-text-editor\" data-id=\"17f633b\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p><span style=\"font-weight: 400;\">Dark store zones have distinct temperature requirements. The frozen zone operates below minus 18 degrees Celsius and the chilled zone between 2 and 8 degrees Celsius. These are served by refrigeration equipment. The ambient zone, which holds packaged food, beverages, household goods, and personal care products, needs to be maintained between 22 and 26 degrees Celsius with relative humidity between 45 and 55 percent.<\/span><\/p><p><span style=\"font-weight: 400;\">FSSAI&#8217;s food safety guidelines require ambient storage areas to be clean, properly ventilated, and free from excessive heat. A dark store ambient zone that regularly exceeds 30 degrees Celsius in summer is not only a product quality problem but a regulatory compliance issue.<\/span><\/p><p><span style=\"font-weight: 400;\"><a href=\"https:\/\/symphonyventicool.com\/blogs\/evaporative-air-cooler-benefits-for-industry\/\"><span style=\"text-decoration: underline;\"><strong>Evaporative industrial air coolers<\/strong><\/span><\/a> address the ambient zone specifically.

Air conditioning requires a sealed building envelope to function efficiently. A dark store is fundamentally semi-open. Loading bay shutters cycle open and closed throughout every operating hour. Delivery riders enter and exit the dispatch area constantly. Fresh stock arrives through roll-up doors. The number of air changes caused by this activity makes it impossible for a sealed AC system to maintain temperature without running at full capacity continuously.<\/span><\/p><p><span style=\"font-weight: 400;\">In practice, dark store operators who install split AC units find that the units struggle to reach their target temperature when loading bays are open, run for extended periods at maximum load, consume far more electricity than anticipated, and require frequent servicing due to the outdoor air exposure. The economics break down quickly, particularly for operators managing dozens of locations.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-64517f9 elementor-widget elementor-widget-html\" data-id=\"64517f9\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"html.default\">\n\t\t\t\t\t<!-- Other article -->\r\n<div class=\"article-container\">\r\n  <div class=\"article-box\">\r\n    <div class=\"article-content\">\r\n      <p class=\"article-label\">Read Our Article<\/p>\r\n      <a href=\"https:\/\/symphonyventicool.com\/blogs\/top-discharge-vs-side-discharge-industrial-evaporative-air-coolers\/\" target=\"_blank\" class=\"article-link\">\r\n        <u>Top Discharge vs. Side Discharge Industrial Evaporative Air Coolers<\/u>\r\n      <\/a>\r\n    <\/div>\r\n  <\/div>\r\n<\/div>\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-ee566cc e-flex e-con-boxed e-con e-parent\" data-id=\"ee566cc\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-23b2103 elementor-widget elementor-widget-heading\" data-id=\"23b2103\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\"><span class=\"ez-toc-section\" id=\"How_an_Industrial_Evaporative_Air_Cooler_Works_in_a_Dark_Store\"><\/span>How an Industrial Evaporative Air Cooler Works in a Dark Store<span class=\"ez-toc-section-end\"><\/span><\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-571cda3 elementor-widget elementor-widget-heading\" data-id=\"571cda3\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Step-by-Step Cooling Process<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-05b27a7 elementor-widget elementor-widget-text-editor\" data-id=\"05b27a7\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<ul><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Hot outdoor air at 35 to 42 degrees Celsius during Indian summer enters the Symphony <a href=\"https:\/\/symphonyventicool.com\/industrial-ducting-cooler-movicool-xxl.php\"><span style=\"text-decoration: underline;\"><strong>industrial cooler<\/strong><\/span><\/a> through a pre-filter that removes dust and airborne particles.<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The filtered air passes through Symphony&#8217;s CELdek evaporative pads, which are continuously wetted by a recirculating water pump.<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Water evaporates from the pad surface, absorbing heat from the air.

During India&#8217;s monsoon season from July to September, when outdoor relative humidity climbs above 70 percent in most cities, the temperature drop achievable through evaporation reduces to 3 to 5 degrees Celsius rather than 8 to 12 degrees. The units continue to provide ventilation, fresh air circulation, and partial cooling during this period.<\/span><\/p><p><span style=\"font-weight: 400;\">For dark store operators, the practical recommendation for monsoon months is to reduce the water pump flow rate to lower moisture addition to the incoming air, maintain exhaust fan operation to ensure through-flow, and use the units in ventilation mode during the highest-humidity hours.
